godan verb (-u)
fight with; contend with
Rare literary compound verb meaning to engage in a struggle or conflict with someone or something. Modern Japanese typically uses 争う or 戦う separately, or phrases like 争って戦う.
彼らは長年、土地の権利を巡って争い戦った。
They fought and contended over land rights for many years.
Compound of 争う (to dispute, compete) and 戦う (to fight). The exact historical derivation is uncertain; it appears in older literary texts as an emphatic expression of conflict.
