Meet a host who presents nothing trendy (6)
I believe the answer is:
adjoin
'meet' is the definition.
(adjoining is a kind of meeting)
'a host who presents nothing trendy' is the wordplay.
'host who presents' becomes 'dj'.
'nothing' becomes 'o' (looks like zero - 0).
'trendy' becomes 'in'.
'a'+'dj'+'o'+'in'='ADJOIN'
(Other definitions for adjoin that I've seen before include "Lie next to" , "20 down" , "Butt up against" , "Be nineteen [NEXT]" , "Be next to, say building" .)
