A word can be generally defined as a basic element of language that carries an objective or practical meaning, can be used on its own, and is uninterruptible. Despite the fact that language speakers often have an intuitive grasp of what a word is, there is no consensus among linguists on its definition and numerous attempts to find specific criteria of the concept remain controversial. Different standards have been proposed, depending on the theoretical background and descriptive context. Some linguists argue, however, that it is possible to create consistent definitions of "word" at different levels of description, for example based on phonological, grammatical or orthographic basis, while others suggest that the concept is simply a convention.

The concept of "word" is distinguished from that of a morpheme, which is the smallest unit of language that has a meaning, even if it cannot stand on its own. Words are made out of at least one morpheme. Morphemes can also be joined to create other words in a process of morphological derivation. In English and many other languages, the morphemes that make up a word generally include at least one root (such as "rock", "god", "type", "writ", "can", "not") and possibly some affixes ("-s", "un-", "-ly", "-ness"). Words with more than one root ("[type][writ]er", "[cow][boy]s", "[tele][graph]ically") are called compound words. In turn, words are combined to form other elements of language, such as phrases ("a red rock", "put up with"), clauses ("I threw a rock"), and sentences ("I threw a rock, but missed").

In many languages, the notion of what constitutes a "word" may be learned as part of learning the writing system. This is the case for the English language, and for most languages that are written with alphabets derived from the ancient Latin or Greek alphabets. In English orthography, the letter sequences "rock", "god", "write", "with", "the", and "not" are considered to be single-morpheme words, whereas "rocks", "ungodliness", "typewriter", and "cannot" are words composed of two or more morphemes ("rock"+"s", "un"+"god"+"li"+"ness", "type"+"writ"+"er", and "can"+"not").

Definitions and meanings

Further information: Lexeme and Lemma (morphology)

Since the beginning of the study of linguistics, numerous attempts at defining what a word is have been made, with many different criteria. However, no satisfying definition has yet been found to apply to all languages and at all levels of linguistic analysis. It is, however, possible to find consistent definitions of "word" at different levels of description. These include definitions on the phonetic and phonological level, that it is the smallest segment of sound that can be theoretically isolated by word accent and boundary markers; on the orthographic level as a segment indicated by blank spaces in writing or print; on the basis of morphology as the basic element of grammatical paradigms like inflection, different from word-forms; within semantics as the smallest and relatively independent carrier of meaning in a lexicon; and syntactically, as the smallest permutable and substitutable unit of a sentence.

In some languages, these different types of words coincide and one can analyze a "phonological word" as essentially the same as "grammatical word". However, in other languages they may correspond to elements of different size. Much of the difficulty stems from the eurocentric bias, as languages from outside of Europe may not follow the intuitions of European scholars. Some of the criteria for "word" developed can only be applicable to languages of broadly European synthetic structure. Because of this unclear status, some linguists propose avoiding the term "word" altogether, instead focusing on better defined terms such as morphemes.

Dictionaries categorize a language's lexicon into individually listed forms called lemmas. These can be taken as an indication of what constitutes a "word" in the opinion of the writers of that language. This written form of a word constitutes a lexeme. The most appropriate means of measuring the length of a word is by counting its syllables or morphemes. When a word has multiple definitions or multiple senses, it may result in confusion in a debate or discussion.

Phonology

Some theorists propose that a word can be defined on phonological grounds as a unit larger or equal to a syllable, which can be distinguished based on segmental or prosodic features or through its interactions with phonological rules. In Walmatjari, an Australian language, roots or suffixes may have only one syllable but a phonologic word must have at least two syllables. A disyllabic verb root may take a zero suffix, e.g. luwa-ø 'hit!', but a monosyllabic root must take a suffix, e.g. ya-nta 'go!'. In the Pitjantjatjara dialect of the Wati language, a word-medial syllable can end with a consonant but a phonological word must end with a vowel.

In most languages, stress may serve a criterion for a phonological word. In languages with a fixed stress, it is possible to ascertain word boundaries from its location. In languages with phonemic stress, although it is impossible to predict word boundaries from stress alone, there will be just one syllable with primary stress per word, which allows for determining the total amount of words in an utterance.

Many phonological rules operate only within a phonological word or specifically across word boundaries. In Hungarian, dental consonants /d/, /t/, /l/ or /n/ assimilate to a following semi-vowel /j/, yielding the corresponding palatal sound, but only within one word. Conversely, external sandhi rules act across word boundaries. The prototypical example of this rule comes from Sanskrit; however, initial consonant mutation in contemporary Celtic languages or the linking r phenomenon in some non-rhotic English dialects can also be used to illustrate word boundaries.

Grammar

Grammatical words were proposed to consist of a number of grammatical elements which occur together and not in separate places within a clause, in a fixed order, and have a conventional meaning. However, there are exceptions to all of these these criteria.

Single words have a fixed internal structure; when the structure is changed, the meaning of the word also changes. In Dyirbal, which can use many derivational affixes with its nouns, there are the dual suffix -jarran and the suffix -gabun meaning "another". With the noun yibi they can be arranged into yibi-jarran-gabun ("another two women") or yibi-gabun-jarran ("two other women") but changing the suffix order also changes their meaning. Speakers of a language also usually associate a specific meaning with a word and not a single morpheme. For example, when asked to talk about untruthfulness they rarely focus on the meaning of morphemes such as -th or -ness.

Semantics

Leonard Bloomfield introduced the concept of "Minimal Free Forms" in 1928. Words are thought of as the smallest meaningful unit of speech that can stand by themselves. This correlates phonemes (units of sound) to lexemes (units of meaning). However, some written words are not minimal free forms as they make no sense by themselves (for example, the and of). Some semanticists have put forward a theory of so-called semantic primitives or semantic primes, indefinable words representing fundamental concepts that are intuitively meaningful. According to this theory, semantic primes serve as the basis for describing the meaning, without circularity, of other words and their associated conceptual denotations.

Features

In the Minimalist school of theoretical syntax, words (also called lexical items in the literature) are construed as "bundles" of linguistic features that are united into a structure with form and meaning. For example, the word "koalas" has semantic features (it denotes real-world objects, koalas), category features (it is a noun), number features (it is plural and must agree with verbs, pronouns, and demonstratives in its domain), phonological features (it is pronounced a certain way), etc.

Orthography

Words made out of letters, divided by spaces.

In languages with a literary tradition, the question of what is considered a single word is influenced by orthography. Word separators, typically spaces and punctuation marks are common in modern orthography of languages using alphabetic scripts, but these are a relatively modern development in the history of writing. In character encoding, word segmentation depends on which characters are defined as word dividers. In English orthography, compound expressions may contain spaces. For example, ice cream, air raid shelter and get up each are generally considered to consist of more than one word (as each of the components are free forms, with the possible exception of get), and so is no one, but the similarly compounded someone and nobody are considered single words.

Sometimes, languages which are close grammatically will consider the same order of words in different ways. For example, reflexive verbs in the French infinitive are separate from their respective particle, e.g. se laver ("to wash oneself"), whereas in Portuguese they are hyphenated, e.g. lavar-se, and in Spanish they are joined, e.g. lavarse.

Not all languages delimit words expressly. Mandarin Chinese is a highly analytic language with few inflectional affixes, making it unnecessary to delimit words orthographically. However, there are many multiple-morpheme compounds in Mandarin, as well as a variety of bound morphemes that make it difficult to clearly determine what constitutes a word. Japanese uses orthographic cues to delimit words, such as switching between kanji (characters borrowed from Chinese writing) and the two kana syllabaries. This is a fairly soft rule, because content words can also be written in hiragana for effect, though if done extensively spaces are typically added to maintain legibility. Vietnamese orthography, although using the Latin alphabet, delimits monosyllabic morphemes rather than words.

Word boundaries

The task of defining what constitutes a "word" involves determining where one word ends and another word begins, that is identifying word boundaries. There are several ways to determine where the word boundaries of spoken language should be placed:

• Potential pause: A speaker is told to repeat a given sentence slowly, allowing for pauses. The speaker will tend to insert pauses at the word boundaries. However, this method is not foolproof: the speaker could easily break up polysyllabic words, or fail to separate two or more closely linked words (e.g. "to a" in "He went to a house").
• Indivisibility: A speaker is told to say a sentence out loud, and then is told to say the sentence again with extra words added to it. Thus, I have lived in this village for ten years might become My family and I have lived in this little village for about ten or so years. These extra words will tend to be added in the word boundaries of the original sentence. However, some languages have infixes, which are put inside a word. Similarly, some have separable affixes: in the German sentence "Ich komme gut zu Hause an", the verb ankommen is separated.
• Phonetic boundaries: Some languages have particular rules of pronunciation that make it easy to spot where a word boundary should be. For example, in a language that regularly stresses the last syllable of a word, a word boundary is likely to fall after each stressed syllable. Another example can be seen in a language that has vowel harmony (like Turkish): the vowels within a given word share the same quality, so a word boundary is likely to occur whenever the vowel quality changes. Nevertheless, not all languages have such convenient phonetic rules, and even those that do present the occasional exceptions.
• Orthographic boundaries: Word separators, such as spaces and punctuation marks can be used to distinguish single words. However, this depends on a specific language. East-asian writing systems often do not separate their characters. This is the case with Chinese, Japanese writing, which use logographic characters, as well as Thai and Lao, which are abugidas.

Morphology

Main article: Morphology (linguistics)

A morphology tree of the English word "independently".

Morphology is the study of word formation and structure. Words may undergo different morphological processes which are traditionally classified into two broad groups: derivation and inflection. Derivation is a process in which a new word is created from existing ones, often with a change of meaning. For example, in English the verb to convert may be modified into the noun a convert through stress shift and into the adjective convertible through affixation. Inflection adds grammatical information to a word, such as indicating case, tense, or gender.

In synthetic languages, a single word stem (for example, love) may inflect to have a number of different forms (for example, loves, loving, and loved). However, for some purposes these are not usually considered to be different words, but rather different forms of the same word. In these languages, words may be considered to be constructed from a number of morphemes.

In Indo-European languages in particular, the morphemes distinguished are:

• The root.
• Optional suffixes.
• A inflectional suffix.

Thus, the Proto-Indo-European *wr̥dhom would be analyzed as consisting of

1. *wr̥-, the zero grade of the root *wer-.
2. A root-extension *-dh- (diachronically a suffix), resulting in a complex root *wr̥dh-.
3. The thematic suffix *-o-.
4. The neuter gender nominative or accusative singular suffix *-m.

Philosophy

Philosophers have found words to be objects of fascination since at least the 5th century BC, with the foundation of the philosophy of language. Plato analyzed words in terms of their origins and the sounds making them up, concluding that there was some connection between sound and meaning, though words change a great deal over time. John Locke wrote that the use of words "is to be sensible marks of ideas", though they are chosen "not by any natural connexion that there is between particular articulate sounds and certain ideas, for then there would be but one language amongst all men; but by a voluntary imposition, whereby such a word is made arbitrarily the mark of such an idea". Wittgenstein's thought transitioned from a word as representation of meaning to "the meaning of a word is its use in the language."

Classes

Main article: Lexical category

Each word belongs to a category, based on shared grammatical properties. Typically, a language's lexicon may be classified into several such groups of words. The total number of categories as well as their types are not universal and vary among languages. For example, English has a group of words called articles, such as the (the definite article) or a (the indefinite article), which mark definiteness or identifiability. This class is not present in Japanese, which depends on context to indicate this difference. On the other hand, Japanese has a class of words called particles which are used to mark noun phrases according to their grammatical function or thematic relation, which English marks using word order or prosody. The basic bipartite division that is possible for virtually every natural language is that of nouns vs verbs.

The current classification of words into classes is based on the work of Dionysius Thrax, who in the 1st century BC distinguished eight categories: noun, verb, adjective, article, pronoun, preposition, adverb, and conjunction. In Indian grammatical tradition, Pāṇini introduced a similar fundamental classification into a nominal (nāma, suP) and a verbal (ākhyāta, tiN) class, based on the set of suffixes taken by the word. Some words can be controversial, such as slang in formal contexts; misnomers, due to them not meaning what they would imply; or polysemous words, due to the potential confusion between their various senses.

History

In ancient Greek and Roman grammatical tradition, the word was the basic unit of analysis. Different grammatical forms of a given lexeme were studied; however, there was no attempt to decompose them into morphemes. This may have been the result of the synthetic nature of these languages, where the internal structure of words may be harder to decode than in analytic languages. There was also no concept of different kinds of words, such as grammatical or phonological – the word was considered a unitary construct. The word (dictiō) was defined as the minimal unit of an utterance (ōrātiō), the expression of a complete thought.
