When the man takes tea (5)
I believe the answer is:
assam
'tea' is the definition.
(I've seen this before)
'when the man' is the wordplay.
'when' becomes 'as' (eg 'when I walked' means 'as I walked').
'the man' becomes 'sam' (man's name).
'as'+'sam'='ASSAM'
'takes' acts as a link.
(Other definitions for assam that I've seen before include "Tea-growing state in north-east India" , "India tea-producing state" , "NE Indian state (tea)" , "Sort of tea" , "Indian province" .)
