Unable to take flight (8)
I believe the answer is:
wingless
'unable to' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'flight' is the wordplay.
I cannot quite understand how this works, but
'flight' could be 'wing' (wing can mean flight, as in 'on the wing') and 'wing' is found in the answer.
The remaining letters 'less' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'take' is the link.
Can you help me to learn more?
(Another definition for wingless that I've seen is " Incapable of taking off".)
