hopeful adj.

late Old English hopa "confidence in the future," especially "God or Christ as a basis for hope," from hope (v.). From c. 1200 as "expectation of something desired;" also "trust, confidence; wishful desire;" late 14c. as "thing hoped for," also "grounds or basis for hope." Personified since c. 1300. Related: Hopes.

Compare Old Frisian and Middle Dutch hope, Danish haab, Dutch hoop, all from their respective verbs. For forlorn hope, see forlorn.

word-forming element attached to nouns (and in modern English to verb stems) and meaning "full of, having, characterized by," also "amount or volume contained" (handful, bellyful); from Old English -full, -ful, which is full (adj.) become a suffix by being coalesced with a preceding noun, but originally a separate word. Cognate with German -voll, Old Norse -fullr, Danish -fuld. Most English -ful adjectives at one time or another had both passive ("full of x") and active ("causing x; full of occasion for x") senses.

It is rare in Old English and Middle English, where full was much more commonly attached at the head of a word (for example Old English fulbrecan "to violate," fulslean "to kill outright," fulripod "mature;" Middle English had ful-comen "attain (a state), realize (a truth)," ful-lasting "durability," ful-thriven "complete, perfect," etc.).

1630s, "in a hopeful manner, with grounds of expectation for success," from hopeful + -ly (2). As a replacement for the admittedly awkward it is to be hoped that, attested from 1932 but avoided by careful writers.
