A noted attempt for oneself (3)
I believe the answer is:
ego
'oneself' is the definition.
(I've seen this in another clue)
'a noted attempt' is the wordplay.
I cannot quite understand how this works, but
'attempt' could be 'go' (go is a kind of attempt) and 'go' is found in the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for ego that I've seen before include "(Self-assertive) personality" , "Personal pride" , "Selfishness" , "One's self image" , "Aspect of the personality" .)
