Food for number to tuck into, as intended (5)
I believe the answer is:
meant
'as intended' is the definition.
(I've seen this before)
'food for number to tuck into' is the wordplay.
'food for' becomes 'meat' (I am not sure about this - if you are sure you should believe this answer much more).
'number' becomes 'n' (n can represent any number).
'to tuck into' means one lot of letters goes inside another.
'meat' going around 'n' is 'MEANT'.
Can you help me to learn more?
(Other definitions for meant that I've seen before include "intimated" , "designed" , "Had as intention or purpose" , "Intentional" , "Intended, had in mind" .)
