Come into somebody else's land perhaps (8)
I believe the answer is:
encroach
'come' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Perhaps you can see a link between them that I don't see?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for encroach that I've seen before include "Gradually intrude (on person's area)" , "Advance beyond the usual limit" , "Go past a normal limit" , "Invade" , "Tread on someone's toes" .)
