Favouring interrupting worker, but not now (6)
I believe the answer is:
before
'not now' is the definition.
I can't tell whether this defines the answer.
'favouring interrupting worker' is the wordplay.
'favouring' becomes 'for' (to be 'for' something is to be in favour of it).
'interrupting' indicates putting letters inside.
'worker' becomes 'bee' (a worker bee).
'for' inserted inside 'bee' is 'BEFORE'.
'but' acts as a link.
Can you help me to learn more?
(Other definitions for before that I've seen before include "Previously ? in front" , "In front of (something)" , "In advance" , "Prior to" , "Earlier than something" .)
