Recommends a party including very small titbits? (9)
I believe the answer is:
advocates
'recommends' is the definition.
('advocate' can be a synonym of 'recommend')
'a party including very small titbits?' is the wordplay.
'party' becomes 'do' (do can informally mean a party).
'including' means one lot of letters goes inside another.
'very' becomes 'v' (abbreviation).
'small titbits?' becomes 'cates' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'do' enclosing 'v' is 'dvo'.
'a'+'dvo'+'cates'='ADVOCATES'
Can you help me to learn more?
(Other definitions for advocates that I've seen before include "Recommends" , "briefs?" .)
