U-turn in the wrong lane ultimately is incorrect (6)
I believe the answer is:
untrue
'incorrect' is the definition.
(I've seen this before)
'u-turn in the wrong lane ultimately' is the wordplay.
I cannot quite understand how this works, but
'u' is present in the answer.
an anagram of 'turn' is 'ntru' which is located in the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'is' acts as a link.
Can you help me to learn more?
(Other definitions for untrue that I've seen before include "Not in accordance with fact" , "Counter-factual" , "Sleeping around" , "False or crooked" , "Spurious" .)
