Romantic aid elicits barking (10)
I believe the answer is:
idealistic
'romantic' is the definition.
(thesaurus)
'aid elicits barking' is the wordplay.
'barking' indicates an anagram (UK slang for mad).
'aid'+'elicits'='aidelicits'
'aidelicits' anagrammed gives 'IDEALISTIC'.
(Other definitions for idealistic that I've seen before include "Striving for perfection" , "Naively impractical" , "Seeking the best" , "High-minded - italicised (anag)" , "Impracticable" .)
