أُحَادَ

[accusative of أُحَادُ] is imperfectly decl., because of its deviation from its original, (S, K,) both in form and in meaning; (S;) [being changed in form from وَاحِدًا, and in meaning from اوَاحِدًا: (see ثُلَاثَ:)] you say, جَاوءُوا أُحَادَ أُحَادَ, [احاد being repeated for the purpose of corroboration,] meaning, They came one [and] one, one [and] one; or one [by] one, one [by] one. (S, K.) The diminutive of أُحَادُ is ↓ أُحَيِّدٌ, perfectly decl., like ثُلَيِّثٌ [q. v.] &c. (S, in article ثلث.)
