جثو ند جثى

6 تَجَاثَوْا عَلَى الرُّكَب تجاثوا علي الركب [ They sat together upon their knees ], (S, K,) in contending or disputing; inf. n. مُجَاثَاةٌ and جِثَاآءٌ, which are [properly inf. ns. of 3, but are] thus used as inf. ns. of a verb to which they do not conform. (TA.) ― -b2- التَّجَاثِى فِى اـِشَالَةِ الحَجَرِ is like التَّجَاذِ ى [ The vying, one with another, in lifting the stone, for trial of strength ]. (TA.)
