From 中期英語 *ripenen, extended form of ripen, from 古期英語 rīpian. In the modern form, equivalent to ripe + -en (inchoative and factitive suffix). As in several other verbs, the alteration seems to have occurred during the time when the infinitive and plural ending -en was in the process of being lost (and was thus open to reinterpretation). The earliest attestation is deverbal 中期英語 ripening (“causing ripeness, ripening”).
ripen (third-person singular simple present ripens, present participle ripening, simple past and past participle ripened)
