Require massage, you say? (4)
I believe the answer is:
need
'require' is the definition.
(I know that require can be written as need)
'massage you say?' is the wordplay.
'massage' becomes 'knead' (synonyms).
'you say?' shows a homophone (sound like).
'knead' sounds like 'NEED'.
(Other definitions for need that I've seen before include "Penury" , "Want - require(ment)" , "Necessity" , "destitute state" , "Call" .)
