Altairn.

Brit.

/alˈtɛː/,

/ˈaltɛː/, U.S.

/ˈælˌtɛ(ə)r/,

/ˈɑlˌtɛ(ə)r/

Forms:

α. 1500s Alcair, 1700s– Altair.

β. 1700s– Atair.

Origin: A borrowing from Arabic. Etymons: Arabic al-ṭa'īr, al-nasr al-ṭa'īr.

Etymology: < Arabic al-ṭa'īr (in al-nasr al-ṭa'īr, literally ‘the flying eagle’ < al the + nasr eagle + al the + ṭa'īr flying, active participle of ṭāra to fly). Compare post-classical Latin Altair (1600 or earlier), French Altaïr (1659 or earlier as †Altair).The form Alcair probably reflects the frequent transcription of the Arabic etymon as Alcair in post-classical Latin astronomical texts (although this is apparently first attested slightly later than in English: 1600 or earlier), in which medial -c- probably attempts to represent the Arabic emphatic dental plosive ṭ . The β. forms ultimately reflect the pronunciation of the Arabic etymon, in which the l of the article is assimilated to the initial consonant of the following word; compare post-classical Latin Attayro (1646 or earlier), Atair (1662 or earlier), German Atair (1781 or earlier).

Astronomy.

The star α Aquilae, a white star that is the brightest in the constellation Aquila and the twelfth brightest in the sky.Altair is one of the three bright stars (along with Vega and Deneb) that form the northern hemisphere's ‘Summer Triangle’. It is one of the closest of the visible stars to the earth, and rotates exceptionally rapidly.
