Old English fullfyllan "fill up" (a room, a ship, etc.), "make full; take the place of (something)," from full (adj.), here perhaps with a sense of "completion" + fyllan (see fill (v.), which is ultimately from the same root). Used from mid-13c. in reference to prophecy (probably translating Latin implere, adimplere). From mid-13c. as "do, perform; carry out, consummate, carry into effect;" from c. 1300 as "complete, finish; satiate, satisfy, gratify." Related: Fulfilled; fulfilling. Modern English combinations with full tend to have it at the end of the word (as -ful), but this is a recent development and in Old English it was more common at the start, but this word and fulsome appear to be the only survivors.

full (adj.)youdaoicibaDictYouDict
Old English full "containing all that can be received; having eaten or drunk to repletion; filled; perfect, entire, utter," from Proto-Germanic *fulla- "full" (cognates: Old Saxon full, Old Frisian ful, Dutch vol, Old High German fol, German voll, Old Norse fullr, Gothic fulls), from PIE *pele- (1) "to fill" (see poly-). Related: Fuller; fullest.

"to tread or beat cloth to cleanse or thicken it," late 14c., from Old French foler, fouler "trample on, press," from Latin fullo "fuller, launderer," also a kind of beetle, a word of unknown etymology.
