أَرْعَى
1.
[apparently More, and most, merciful or compassionate; from أَرْعَيْتُ عَلَيْهِ, though by rule it should be formed from an unaugmented verb according to many of the grammarians:
2.
and hence, being nearly synonym with أَرْفَقُ in the primary sense, synonym with this latter, or nearly so, in a secondary sense]. You say, أَمْرُ كَذَا أَرْفَقُ بِى
وَأَرْعَى عَلَىَّ [apparently meaning (assumed tropical:) This affair is more, or most, easy and convenient to me]. (TA.)
