Synonym discussion
Sense: adverb/1
All four adverbs describe an attempt that does not succeed, but they differ in tone and emphasis. 'Unsuccessfully' is the most neutral and widely used — it states the outcome without judging the effort itself. 'Vainly' carries a literary or even dramatic tone, often suggesting that the attempt was doomed or empty (e.g., 'She vainly tried to change his mind'). 'Fruitlessly' focuses on the effort being thorough but wasted, like hard labour that yields nothing ('The team searched fruitlessly for survivors'). 'Futilely' is the strongest — it implies the attempt never had a real chance because the situation made success impossible ('He futilely argued against the court's final decision'). Choose 'unsuccessfully' for general reporting, and the others when you want to add emotional colour or philosophical judgment about the attempt.

Etymology
Formed from the prefix un- (meaning 'not') added to 'successfully', which itself comes from 'successful' + '-ly'. The root 'success' traces back through Latin successus ('a good result, an outcome') to succedere ('to come after, to go near to'). The modern sense of 'achieving a desired aim' developed in English during the 16th century.
