Ordered temp's beer for a few weeks (9)
I believe the answer is:
september
'a few weeks' is the definition.
'ordered temp's beer' is the wordplay.
'ordered' indicates an anagram.
'temps'+'beer'='tempsbeer'
'tempsbeer' with letters rearranged gives 'SEPTEMBER'.
'for' acts as a link.
(Other definitions for september that I've seen before include "The longest month?" , "Tempers be changed this month?" , "It follows 3" , "about 4 weeks" , "- Song (Kurt Weill)" .)
