Take a few moments, now and then (9)
I believe the answer is:
sometimes
'now and then' is the definition.
(I've seen this before)
'take a few moments' is the wordplay.
I cannot quite understand how this works, but
'few' could be 'some' (associated in meaning) and 'some' is present in the answer.
'moments' could be 'times' (time is a kind of moment) and 'times' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for sometimes that I've seen before include "Not always" , "Seem moist (anag.)" , "On occasion" , "Occasionally available" .)
