Ā, lowercase ā, is a grapheme, a Latin A with a macron, is used in several orthographies.
In some languages Ā is used to denote a long A. Examples are the Baltic languages, Polynesian languages, some romanizations of Japanese (rōmaji), Persian, Pashto, Assyrian Neo-Aramaic (which represents a long A sound) and Arabic, and some Latin texts (especially for learners). In Romanised Mandarin Chinese (pinyin) it is used to represent A spoken with a level high tone (first tone). It is used in some orthography-based transcriptions of English to represent the diphthong /eɪ/ (see Vowel length § Traditional long and short vowels in English orthography), and also in commercial names such as Drāno and Powerāde.
In the International Alphabet of Sanskrit Transliteration, Ā represents the open back unrounded vowel, आ, not to be confused with the similar Devanagari character for the mid central vowel, अ.
In the languages other than Sanskrit,[1] Ā is sorted with other A's and is not considered a separate letter. The macron is only considered when sorting words that are otherwise identical. For example, in Māori, tāu (meaning your) comes after tau (meaning year), but before taumata (hill).
