Make an effort to take in launch of aircraft carrier (4)
I believe the answer is:
tray
'carrier' is the definition.
(I've seen this before)
'make an effort to take in launch of aircraft' is the wordplay.
I cannot really see how this works, but
'an' could be 'a' and 'a' is found within the answer.
'effort' could be 'try' (synonyms) and 'try' is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tray that I've seen before include "canteen item" , "Flat plate for carrying things" , "Flattish carrying board" , "Shallow receptable for carrying something" , "three" .)
