vainly + verb

be + in vain

用法筆記

He tried in vain.' or 'He tried vainly.
'vain' is an adjective and cannot serve as an adverb on its own.
Vainly, his attempts helped nobody.' (ambiguous position)
His attempts vainly helped nobody.
'vainly' usually sounds more natural when placed right before or after the main verb.
