French in luck after missing initial boost (7)
I believe the answer is:
enhance
'boost' is the definition.
(I've seen this before)
'french in luck after missing initial' is the wordplay.
'french in' becomes 'en' (French for 'in').
'luck' becomes 'ha' (I can't explain this - if you can you should give a lot more credence to this answer).
'after' becomes 'once' (once can mean immediately after).
'missing initial' means to remove the first letter.
'once' with its initial letter taken off is 'nce'.
'en'+'ha'+'nce'='ENHANCE'
Can you help me to learn more?
(Other definitions for enhance that I've seen before include "improve things" , "Improve the quality of (something)" , "Add function, appeal, to" , "Increase in power" , "Boost" .)
