مَصَارّ

[apparently an irregular plural of مَصِيرٌ, and therefore without tenween,] The أَمْعَاء [or guts, bowels, or intestines, into which the food passes from the stomach]. (M, K.) One says, شَرِبَ حَتَّى مَلَأَ مَصَارَّهُ, meaning [He drank until he filled] his أَمْعَاء: mentioned by AHn on the authority of IAar, with no more explanation than this. (M.)
