Playing Steinway, oblivious to vacuous intern describing clammy appearance (6)
I believe the answer is:
sweaty
'steinway oblivious to vacuous intern describing clammy appearance' is the definition.
I can't tell whether this defines the answer.
'playing' is the wordplay.
I cannot really understand how this works, but
'playing' could be 'at' (I've seen this in other clues) and 'at' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for sweaty that I've seen before include "like some athletes in competition?" , "Showing effects of fever" , "Given to perspiring, in moist state" , "Damp with perspiration" , "affected by the heat" .)
