Trick and joke, reportedly, with clog (7)
I believe the answer is:
congest
'clog' is the definition.
(synonyms)
'trick and joke reportedly' is the wordplay.
'trick' becomes 'con' (I've seen this before).
'and' is a charade indicator (letters next to each other).
'joke' becomes 'jest' (synonyms).
'reportedly' shows a homophone (sound like).
'jest' is a homophone of 'gest'.
'con'+'gest'='CONGEST'
'with' is the link.
(Other definitions for congest that I've seen before include "fill with traffic?" , "Become overcrowded" , "Block up" , "Become or cause to become obstructed" .)
