Some weeks of term are quieter (6)
I believe the answer is:
softer
'quieter' is the definition.
('soft' is associated in meaning with 'quiet')
'some weeks of term' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'SOFTER' is hidden in the letters of 'weeks of term'.
'are' is the link.
(Other definitions for softer that I've seen before include "More pliable or malleable" , "Less firm, loud" , "Less hard, more malleable" , "Less hard, more yielding" .)
