US star also coming back for cigar (7)
I believe the answer is:
cheroot
'for cigar' is the definition.
(cheroot is a kind of cigar)
'us star also coming back' is the wordplay.
'us star' becomes 'cher' (I can't explain this - if you can you should believe this answer much more).
'also' becomes 'too' (synonyms).
'coming back' shows that the letters should be reversed in order.
'too' back-to-front is 'oot'.
'cher'+'oot'='CHEROOT'
Can you help me to learn more?
(Other definitions for cheroot that I've seen before include "Type of cigar" , "With both ends cut off squarely, is smoked" , "Square-cut cigar" , "Cigar cut at both ends" , "Small cigar" .)
