Etymology 1

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 quer?la, querella (“dispute; argument; complaint, grievance; legal complaint; lament; illness”), from quer? + -?la, -ella (suffix forming nouns).
