rinse

From Middle English rinsen, rincen, rencen (“to rinse”), from Old French rincier, reinser, Old Northern French raïncer (“to rinse, cleanse”). Of contested origin. Possibly from Old Norse hreinsa, from Proto-Germanic *hrainisōną (“to clean, purify”), from Proto-Indo-European *krey- (“to separate, divide”). Alternatively from a dissimilation of Old French recincier, from Latin recentare (“to make fresh”). Cognate with French rincer. From the Germanic verb are Danish rense, Norwegian rense, Swedish rensa (all “to clean”), Old High German reinisōn (“to clean, purify, atone”). It is related to German rein (“pure”), Gothic 𐌷𐍂𐌰𐌹𐌽𐍃 (hrains, “clean”), and English riddle. The Latin verb is related to recent.
