One’s implicated in law, successively withdrawn (8)
I believe the answer is:
taciturn
'withdrawn' is the definition.
(I've seen this before)
'one's implicated in law successively' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'i' (roman numeral) and 'i' is present in the answer.
'law' could be 'act' (I've seen this before) and 'act' is found within the remaining letters.
The remaining letters 'turn' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for taciturn that I've seen before include "Reserved and uncommunicative" , "Habitually silent" , "Not inclined to conversation" , "withdrawn" , "Aloof" .)
