Thought of us in a sunny sea area (5)
I believe the answer is:
mused
'thought of' is the definition.
(I've seen this before)
'us in a sunny sea area' is the wordplay.
I cannot quite see how this works, but
'us' is present in the answer.
'sea' could be 'med' (abbreviation of Mediterranean) and 'med' is located in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for mused that I've seen before include "Was absorbed in thought" , "Reflected or pondered" , "Closer" , "Fuddled" , "Contemplated" .)
