Take a month to get some ideas or make a choice (6)
I believe the answer is:
decide
'make a choice' is the definition.
(I've seen this in another clue)
'take a month to get some ideas' is the wordplay.
I cannot quite see how this works, but
'month' could be 'dec' (abbreviation for December) and 'dec' is present in the answer.
The remaining letters 'ide' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'or' acts as a link.
Can you help me to learn more?
(Other definitions for decide that I've seen before include "Make up one's mind" , "Choose" , "Determine - settle" , "Settle conclusively" , "Conclude" .)
