Working at home before entering office (7)
I believe the answer is:
ingoing
'entering office' is the definition.
'ingoing' can be an answer for 'entering' (I've seen this before). I'm not sure about the 'office' bit.
'working at home' is the wordplay.
'working' becomes 'going' (working can mean going or activated).
'at' means one lot of letters go next to another (I've seen this in other clues).
'home' becomes 'in' ('he's home' can mean 'he's in').
'going' put after 'in' is 'INGOING'.
'before' is the link.
Can you help me to learn more?
(Other definitions for ingoing that I've seen before include "Approaching" , "Just elected" , "Making entry" , "Entering" , "Heading inwards" .)
