عَجْلَانُ

[Hence,] قَوْسٌ عَجْلَى A bow of which the arrow is quick [in its flight]. (AHn, K.)

And أُمُّ عَجْلَانَ A certain bird, (S, O, K,) black, but white in the base of the tail, that moves about its tail much, or often; also called الفَتَّاحُ. (O.)

And العَجْلَانُ is [a name of The month] شَعْبَانُ: so called because of the quickness of its passing away and coming to an end; (L, K; [in the latter of which, in some copies, وَنَفَاذِهِ is erroneously put for وَنَفَاذِهِ;]) i. e. because of its seeming short on account of the fast that follows it. (L.)
