Unrealistic, and beyond 1’s capabilities? (2,7,6)
I believe the answer is:
on another planet
'capabilities?' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'unrealistic and beyond 1's' is the wordplay.
I cannot quite understand how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is located in the answer.
'1' could be 'ane' (synonyms) and 'ane' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for on another planet that I've seen before include "Out of touch with reality" , "spaced out?" , "adrift of reality" , "crazy" .)
