Let on about knight being pampered (8)
I believe the answer is:
spoonfed
'being pampered' is the definition.
'let on about knight' is the wordplay.
I cannot quite understand how this works, but
'on' is present in the answer.
'about' could be 'of' and 'of' is found in the remaining letters.
The remaining letters 'sped' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for spoonfed that I've seen before include "Given too much information" , "Spoilt" .)
