quarrel

From Middle English querele (“altercation, dispute; argument, debate; armed combat; trial by combat; basis for dispute, complaint; claim, legal suit; a lament; illness”) [and other forms], from Anglo-Norman querele [and other forms] and Middle French querele, querelle (“altercation, dispute; basis for dispute; side in a dispute; complaint; accusation; legal suit; lament; problem”) (modern French querelle), and from their etymon Latin querēla, querella (“dispute; argument; complaint, grievance; legal complaint; lament; illness”), from querī + -ēla, -ella (suffix forming nouns). querī (“to complain; to bewail, lament; to be indignant”) comes from Proto-Indo-European *ḱwes- (“to puff; to sigh”).

From Middle English querelen (“to dispute, quarrel; to assert one's claims; to rebel”) [and other forms], from querele (noun); see etymology 1. Compare Anglo-Norman, Middle French, and Old French quereler, quereller (“to argue with, dispute; to criticize; to bring a legal suit”) (modern French quereller (“to quarrel, squabble”)).
