Foxtrot by Romeo has to produce disapproving looks (6)
I believe the answer is:
frowns
'looks' is the definition.
(I know this)
'foxtrot by romeo has' is the wordplay.
'foxtrot' becomes 'f' (phonetic alphabet: alpha, bravo, charlie etc.).
'by' is a charade indicator (letters next to each other).
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'has' becomes 'owns' ('own' can be a synonym of 'have').
'f'+'r'+'owns'='FROWNS'
'to produce disapproving' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for frowns that I've seen before include "Scowls" , "Shows displeasure" .)
