فَتِىٌّ

Youthful; or in the prime of life; (Lth, T, S, M, Mgh, Msb, K;) opposite of مُسِنٌّ; (S, Mgh, Msb;) applied to a camel, (T,) or to a beast, (S, Mgh, Msb,) or to anything [i. e. to a beast and to a human being]; (M, K;) or it is like فَتًى [which is applied peculiarly to a human being], but is sometimes applied to a camel: (M:) [this last statement, however, requires confirmation, which I have not been able to find: the epithet is generally known as applied only to a camel or the like:] the feminine is فَتِيَّةٌ; (Lth, T, M, Mgh, Msb, K;) of which the diminutive is ↓ فُتَيَّةٌ: (TA:) and the plural is أَفْتَاءٌ (T, S, Mgh, Msb, TA) and فِتَاءٌ. (M, K, TA. [The former plural, though the more common, is not mentioned in the M nor in the K.])
