Occasionally enhance magazine's cover (7)
I believe the answer is:
nacelle
'cover' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'occasionally enhance magazine's' is the wordplay.
'occasionally' indicates alternate letters (letters taken at regular intervals or occasions).
'magazine' becomes 'elle' (Elle is a magazine).
The alternate letters of 'enhance' are 'nac'.
'nac'+'elle'='NACELLE'
Can you help me to learn more?
(Other definitions for nacelle that I've seen before include "Aircraft engine fairing" , "Streamlined housing on an aircraft" , "part of the aeroplane" , "Aeronautical engineer's housing" , "Aircraft body" .)
