Ā, lowercase ā ("A with macron"), is a grapheme, a Latin A with a macron, used in several orthographies. Ā is used to denote a long A. Examples are the Baltic languages (e.g. Latvian), Polynesian languages, including Māori and Moriori, some romanizations of Japanese, Persian, Pashto, Aten (which represents a long A sound), Arabic, Hebrew, 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 (see ).
