Comment on what you see? (7)
I believe the answer is:
observe
This clue could be a double definition.
'comment on' is the first definition.
'observe' can be an answer for 'comment' (thesaurus). I'm unsure of the 'on' bit.
'you see?' is the second definition.
'observe' can be an answer for 'see?' (I've seen this before). I am unsure of the 'you' bit.
'what' acts as a link.
Can you help me to learn more?
(Other definitions for observe that I've seen before include "What this newspaper does?" , "See - say" , "Espy" , "Notice, watch" , "Keep - watch" .)
