مُرٌّ

Bitter; (S, A, Msb, K;) opposite of حُلْوٌ; (K;) as also ↓ مَرِيرٌ and ↓ مُمِرٌّ: (A:) feminine مُرَّةٌ: (Msb, TA:) plural masculine أَمْرَارٌ, (T, S, M,) and plural feminine مَرَايءِرُ, contr. to rule, (Msb,) because مُرَّةٌ means خَبِيثَةُ الطَّعْمِ [bad-tasted; and the plural of خبيثة is خَبَايءِثُ]. (Msb, voce حُرٌّ.) You say بَقْلَةٌ مُرَّةٌ [A bitter leguminous plant]: and هَذِهِ البَقْلَةُ مِنْ أَمْرَارِ البُقْولِ [This leguminous plant is one of the bitter leguminous plants]. (T.)
