Tin fan broken by minor (6)
I believe the answer is:
infant
'minor' is the definition.
(thesaurus)
'tin fan broken' is the wordplay.
'broken' is an anagram indicator.
'tin'+'fan'='tinfan'
'tinfan' anagrammed gives 'INFANT'.
'by' is the link.
(Other definitions for infant that I've seen before include "Toddler" , "Juvenile" , "Thing in early stage; minor (legal)" , "Tot" , "Child at an early stage of life" .)
