Word History

Etymology

Verb

Middle English fillen, fullen, fellen, going back to Old English fyllan, going back to Germanic *fulljan- (whence also Old Frisian fella "to fill," Old Saxon fullian, Old High German fullen, Old Icelandic fylla, Gothic fulljan), weak verb derivative from the stem of *fulla- full entry 1

Noun

(sense 1) Middle English fille, fulle, felle, going back to Old English fyllu, fyll, going back to Germanic *full-īn- (whence also Middle Dutch volle "full supply, fill," Old High German fullī, follī, Old Icelandic fylli, Gothic ufarfullei "superfluity"), from *fulla- full entry 1 + *-īn-, noun suffix of quality; (sense 2) derivative of fill entry 1

Note: As with other nouns originally formed with the suffix *-īn-, Old English has reclassed the nouns as regular *-ō feminine nouns by association with the suffix *-iþō.
