Indifferent about nerves over time (7)
I believe the answer is:
neutral
'indifferent' is the definition.
(I know that indifferent can be written as neutral)
'nerves over time' is the wordplay.
I cannot quite see how this works, but
'time' could be 't' (abbreviation) and 't' is found within the answer.
The remaining letters 'neural' 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).
'about' is the link.
Can you help me to learn more?
(Other definitions for neutral that I've seen before include "Unaligned" , "having no potential" , "uncommitted to either side" , "Impartial; plug wire" , "without any charge" .)
