Dear Raymond, youll find the costume enclosed (5)
I believe the answer is:
array
'costume enclosed' is the definition.
I can't tell whether this definition defines the answer.
'dear raymond youll find' is the wordplay.
'find' says the answer is hidden in the clue (I've seen 'found' mean this).
'ARRAY' can be found hidden inside 'dear raymond youll'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for array that I've seen before include "Rig up" , "Line up" , "Lay out, arrange" , "Ordered arrangement (of troops)" , "Impressive exhibition" .)
