full: [OE] Full and its verbal derivative fill go back ultimately to the Indo-European base *plē-, which also produced Latin plēnus ‘full’ (source of English plenary, plenty, and replenish, and of French plein and Italian pieno ‘full’) and English complete, deplete [19] (literally ‘unfill, empty’), implement, plebeian, plethora, plural, plus, replete [14], supply, and surplus [14].
The Indo- European derivative *plnós passed into prehistoric Germanic as *fulnaz, which eventually became *fullaz, source of German voll, Dutch vol, and Swedish and English full. Fulfil dates from the late Old English period; it originally meant literally ‘fill full, fill up’. => complete, deplete, fill, implement, plenty, plethora, plural, plus, replete, supply, surplus
full (adj.)
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.
The adverb is Old English ful "very, fully, entirely, completely" and was common in Middle English (full well, full many, etc.); sense of "quite, exactly, precisely" is from 1580s. Full moon, one with its whole disc illuminated, was Old English fulles monan; first record of full-blood in reference to racial purity is from 1812. Full house is 1710 in the theatrical sense, 1887 in the poker sense (three of a kind and a pair, earlier full-hand, 1850). Full-dress (adj.) "appropriate to a formal occasion" is from 1761, from the noun phrase.
full (v.)
"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. Perhaps the Middle English word was from Old English agent-noun fullere, which probably was formed from Latin fullo with a native ending.
full (n.)
early 14c., from Old English fyllo, fyllu "fullness (of food), satiety;" also from full (adj.).
