Commence, for example, in a receptacle ... (5)
I believe the answer is:
begin
'commence' is the definition.
(I know that commence can be written as begin)
'example in a receptacle' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'in' means one lot of letters goes inside another.
'a receptacle' becomes 'bin' (I've seen this before).
'eg' going inside 'bin' is 'BEGIN'.
'for' is the link.
(Other definitions for begin that I've seen before include "Israeli statesman" , "Commence" , "Israeli prime minister who shared the Nobel Peace Prize with President Sadat" , "Found" , "Get cracking" .)
