The noun for “wind”, attested only in the plural (bawîb) and subjective plural (bawîba) forms (SD/247, SD/312). Its plural form indicates that it is a strong-noun (Strong I), so its final vowel must be short, but in theory it could be any of a, i or u, each of which would be replaced by long î in plural nouns. Nouns with identical vowels are more common, however, so *bawab is the most likely singular form, though as Helge Fauskanger points out (AL/Adûnaic) the normal form could also be the weak noun *bawâb with a poetic strong plural (SD/435).
