Strife, conflict, or quarreling; contention between parties.
From Old French 'estrif', derived from 'estriver' meaning 'to quarrel'. Related to the modern English word 'strife', which eventually replaced this form.
'Estrif' and 'strife' are actually the same word at different stages—English speakers gradually dropped the initial 'es-' prefix because it became redundant.
