An alpha privative or, rarely,[1] privative a (from Latin alpha prīvātīvum, from Ancient Greek α στερητικόν) is the prefix a- or an- (before vowels) that is used in Greek and in English words borrowed from Greek to express negation or absence, for example atypical, anesthetic, and analgesic.

It is derived from a Proto-Indo-European syllabic nasal *n̥-, the zero ablaut grade of the negation *ne, i.e. /n/ used as a vowel. For this reason, it usually appears as an- before vowels (e.g. an-alphabetism, an-esthesia, an-archy).[2] It shares the same root with the Greek prefix nē- or ne-, in Greek νη- or νε-, that is also privative (e.g. ne-penthe).[3]

It is not to be confused with among other things, an alpha copulative (e.g. a-delphi) or the prepositional component an- (i.e. the preposition ana with ekthlipsis or ellision of its final vowel before a following vowel; e.g. an-ode).


Cognates[edit]

Sanskrit[edit]

The same prefix appears in Sanskrit, also as a-, an-.

Latin[edit]

In Latin, the cognate prefix is in-. The prepositional prefix in- is unrelated.

Germanic languages[edit]

In English and other West Germanic languages, the cognate is un- (or on-).

In North Germanic languages, the -n- has disappeared and Old Norse has ú- (e.g. ú-dáins-akr), Danish and Norwegian have u-, whereas Swedish uses o- (pronounced [u]), and Icelandic and Faroese use the related ó-.

Homonym[edit]

The prefix ἁ- ha- (also - a- from psilosis), copulative a, is nearly homonymous with privative a, but originates from Proto-Indo-European *sm̥.[2]
