Origin
From Middle English offer, from Old English offrian ("offer or make a sacrifice") rather than from Old French offre ("offer"), from offrir, from Latin offerō ("to present, bring before"). Compare North Frisian offer ("sacrifice, donation, fee"), Dutch offer ("offering, sacrifice"), German Opfer ("victim, sacrifice"), Danish offer ("victim, sacrifice"), Icelandic offr ("offering"). See verb below.
From Middle English offren, offrien. In the religious senses inherited from Old English offrian ("to offer, sacrifice, bring an oblation"); otherwise from Old French ofrir. Both ultimately from Latin offerō ("to present, bestow, bring before"), from Latin ob + ferō, from Proto-Indo-European *bʰer-, *bʰrē-, later reinforced by Old French offrir ("to offer"). Cognate with Old Frisian offria ("to offer"), Old Dutch offrōn ("to offer"), German opfern ("to offer"), Old Norse offra ("to offer"). More at ob-, bear.
