Short-sighted setter’s small photo covers last part of video (6)
I believe the answer is:
myopic
'short-sighted' is the definition.
(I've seen this before)
'setter's small photo covers last part of video' is the wordplay.
'setter's' becomes 'my' (belonging to the crossword setter).
'small photo' becomes 'pic' (I've seen this in other clues. I am not sure about the 'small' bit.).
'covers' is an insertion indicator.
'last part of' says to take the final letters.
The last letter of 'video' is 'o'.
'my'+'pic'='mypic'
'mypic' placed around 'o' is 'MYOPIC'.
Can you help me to learn more?
(Other definitions for myopic that I've seen before include "needing help from lens" , "Unable to focus on distant objects" , "Lacking foresight?" , "Short-sighted" , "lack of foresight" .)
