A teacher after a job as a civil servant (10)
I believe the answer is:
postmaster
'a civil servant' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'a teacher after a job' is the wordplay.
'a teacher' becomes 'master' (I've seen this before).
'after' means one lot of letters go next to another.
'a job' becomes 'post' (post is a kind of job).
'master' after 'post' is 'POSTMASTER'.
'as' is the link.
Can you help me to learn more?
(Other definitions for postmaster that I've seen before include "Mail chief" , "who runs a local office?" .)
