رَثْأَةٌ

, (M, TA,) or ↓ رَثْءٌ, (K, [probably a mistranscription,]) (assumed tropical:) Littleness of intelligence or sagacity: (M, K:) and (assumed tropical:) weakness of heart: (M, TA:) and (assumed tropical:) foolishness, or stupidity; (K;) and so ↓ رَثِيْيءَةٌ (Th, M, K) and ↓ مَرْثَأٌ. (TA in article وأب.)

Hence, perhaps, (TA,) the first of these words (رَثْأَةٌ) signifies [also] (assumed tropical:) A certain disease in a camel's shoulder-joint, (K,) in consequence of which he limps. (TA.)
