Fairy girl men led astray (7)
I believe the answer is:
gremlin
'fairy' is the definition.
(gremlin is a kind of fairy)
'girl men led astray' is the wordplay.
'led astray' is an anagram indicator.
'girl'+'men'='girlmen'
'girlmen' anagrammed gives 'GREMLIN'.
(Other definitions for gremlin that I've seen before include "Impish troublemaker" , "Mischievous machine saboteur" , "mischievous type" , "Mischievous sprite" , "aviation spirit?" .)
