Right way to enter - take note (6)
I believe the answer is:
listen
'note' is the definition.
The answer and definition can be both to do with perception as well as being verbs in their base form.
Maybe you can see a link between them that I don't see?
'right way to enter' is the wordplay.
'right' becomes 'lien' (legal right).
'way' becomes 'st' (abbreviation for street).
'to enter' is an insertion indicator.
'lien' placed around 'st' is 'LISTEN'.
'take' is the link.
Can you help me to learn more?
(Other definitions for listen that I've seen before include "Give one's attention" , "Be silent in order to hear" , "what buggers do" , "Respond to a request" , "16 (anag.)" .)
