Olympic athlete to seem angry about weight (7)
I believe the answer is:
swimmer
'olympic athlete' is the definition.
'swimmer' can be an answer for 'athlete' (swimmer is a kind of athlete). I am not sure about the 'olympic' bit.
'seem angry about weight' is the wordplay.
I cannot quite see how this works, but
'weight' could be 'w' (short for weight) and 'w' is present in the answer.
The remaining letters 'simmer' 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).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for swimmer that I've seen before include "Person moving through water" , "Eg, Captain Webb" , "A mover in water" , "One doing crawl, say" , "Michael Phelps, say" .)
