Like a sunny area with some pictorial possibilities (6)
I believe the answer is:
tropic
'like a sunny area' is the definition.
I can't judge whether this definition defines the answer.
'with some pictorial possibilities' is the wordplay.
'with' means one lot of letters goes inside another.
'some' indicates taking the first letters.
'possibilities' becomes 'troic' (I can't explain this - if you can you should give a lot more credence to this answer).
The initial letter of 'pictorial' is 'p'.
'p' going within 'troic' is 'TROPIC'.
Can you help me to learn more?
(Other definitions for tropic that I've seen before include "hot spot" , "Line of latitude determined by the solstice" , "Cancer is one, Capricorn another" , "Either that of Capricorn or Cancer" , "Parallel of latitude about 25o N or S" .)
