Enter the dock and perjure oneself on trial (3,2)
I believe the answer is:
lie up
'enter' is the definition.
Both the answer and definition are verbs in their base form.
Perhaps you can see an association between them that I don't see?
'dock and perjure oneself on trial' is the wordplay.
I cannot quite see how this works, but
'perjure' could be 'lie' (I've seen this before) and 'lie' is present in the answer.
The remaining letters 'up' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'the' is the link.
Can you help me to learn more?
(Other definitions for lie up that I've seen before include "Stay in bed" , "out of commission" , "(Of ship) go into dock" , "Berth" .)
