Take action with intoxicated person that's first by entrance (8)
I believe the answer is:
litigate
'take action' is the definition.
(I've seen this before)
'intoxicated person that's first by entrance' is the wordplay.
'intoxicated person' becomes 'lit' (I can't justify this - if you can you should believe this answer much more).
'that's first' becomes 'i' (I in Roman numerals eg Elizabeth I).
'by' means one lot of letters go next to another.
'entrance' becomes 'gate' (type of entrance).
'lit'+'i'+'gate'='LITIGATE'
'with' is the link.
Can you help me to learn more?
(Other definitions for litigate that I've seen before include "Engage in legal proceedings" , "Contest at law" , "Go to law" , "take action" , "Dispute by law" .)
