Son possibly saw somewhere to sit (5)
I believe the answer is:
stool
'son' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'saw somewhere to sit' is the wordplay.
I cannot really understand how this works, but
'to' is present in the answer.
The remaining letters 'sol' 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).
'possibly' acts as a link.
Can you help me to learn more?
(Other definitions for stool that I've seen before include "Motion" , "Armless seat" , "Backless chair" , "Seat without a back" , "Three-legged backless seat" .)
