At home, gets in the way of one’s usual procedure (7)
I believe the answer is:
routine
'procedure' is the definition.
(I know that routine is a type of procedure)
'at home gets in the way' is the wordplay.
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'gets in' indicates putting letters inside.
'the way' becomes 'route' (route is a kind of way).
'in' placed into 'route' is 'ROUTINE'.
'of one's usual' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for routine that I've seen before include "Unvarying set of actions" , "Fixed programme" , "every day" , "Unvarying, habitual procedure" , "Unvarying programme" .)
