Lightweight laptop packaged by mailer (7)
I believe the answer is:
slender
'lightweight' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'laptop packaged by mailer' is the wordplay.
I cannot quite see how this works, but
'laptop' could be 'l' (top of the word 'lap') and 'l' is present in the answer.
'mailer' could be 'sender' (I've seen this in another clue) and 'sender' is located in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for slender that I've seen before include "Spare" , "short of a pound or two of flesh?" , "Lean" , "Meagre" , "inadequate" .)
