Vacancy for the job of a doorman (7)
I believe the answer is:
opening
This could be a double definition.
'vacancy' is the first definition.
(I've seen this before)
'job of a doorman' is the second definition.
'opening' can be an answer for 'job' (thesaurus). I am not certain of the 'of a doorman' bit.
'for the' is the link.
Can you help me to learn more?
(Other definitions for opening that I've seen before include "Aperture or first night" , "Vacancy" , "break" , "- - time (pub)" , "Vent or opportunity" .)
