(S.) ↓ اِرْعَوَى is of the measure اِفْعَلَلَ [for اِفْعَلَّ]; the two infirm letters not being incorporated, one into the other, because the ى is quiescent: (S: [see also Ham p. 220:]) you say, عَنِ القَبِيحِ ↓ ارعوى, (S, Msb,) or عن الجَهْلِ, (Ham ubi suprà,) He refrained, forbore, or abstained, from bad, or foul, conduct, (S, Msb,) or from ignorance, and reverted therefrom: (Ham:) and ↓ ارعوى [alone] signifies He refrained, forbore, or abstained; and he repented: (Har p. 240:) [see also an ex. in a verse cited voce أَلَا:] accord. to AHei, it is quasi-pass. of رَعَوْتُهُ. (TA.) -A2- [Hence, رَعَوْتُهُ app. signifies I caused him to refrain, forbear, or abstain, &c.]
