Get in the way? I'm not regularly impolite (7)
I believe the answer is:
intrude
'get in' is the definition.
(intruding is a kind of getting in)
'i'm not regularly impolite' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'impolite' becomes 'rude' ('rude' can be similar in meaning to 'impolite').
'im'+'not'='imnot'
The alternate letters of 'imnot' are 'int'.
'int'+'rude'='INTRUDE'
'the way?' acts as a 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 intrude that I've seen before include "Encroach on others' privacy" , "Come in without invitation" , "Gatecrash" , "Butt in, interfere" , "Come in when not wanted" .)
