Time when battery production may be up in the air? (7,3)
I believe the answer is:
pancake day
'the air?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'time when battery production may be up' is the wordplay.
I cannot quite see how this works, but
'time' could be 'day' (day is a kind of time) and 'day' is found in the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
'battery' could be 'c' (C battery is an example) and 'c' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for pancake day that I've seen before include "Shrove Tues. (colloq.)" , "Shrove Tuesday" .)
