He often has his head in the clouds (5)
I believe the answer is:
pilot
This clue could be a double definition.
'he often' is the first definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'his head in the clouds' is the second definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for pilot that I've seen before include "Ship's guide" , "air traffic controller?" , "Guide, steer" , "Plane operator" , "Test or trial (project or programme)" .)
