Step required to break lock and gain unlawful entry (8)
I believe the answer is:
trespass
'unlawful entry' is the definition.
(I've seen this in another clue)
'step required to break lock and gain' is the wordplay.
I cannot really understand how this works, but
'step' could be 'pas' (I've seen this in another clue) and 'pas' is located in the answer.
'lock' could be 'ress' (I've seen this in another clue) and 'ress' is present in the leftover letters.
A single letter 't' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for trespass that I've seen before include "Invade" , "Wrong" , "Transgress" , "Enter land without permission" , "Go where one shouldn't" .)
