Blocks podcast Curt's boss uploaded (9)
I believe the answer is:
obstructs
'blocks podcast curt's boss uploaded' is the definition.
I can't tell whether this defines the answer.
'blocks podcast curt's boss uploaded' is the wordplay.
'blocks' says the answer is hidden in the clue (the answer plugs or blocks part of the clue).
'uploaded' is a reversal indicator.
'stcurtsbo' can be found hidden inside 'podcast curts boss'.
'stcurtsbo' written backwards gives 'OBSTRUCTS'.
(Other definitions for obstructs that I've seen before include "Prevents or hinders passage" , "Blocks" .)
