Nothing's held in trust if there's denial (3)
I believe the answer is:
not
'denial' is the definition.
'nothing's held in trust if' is the wordplay.
I cannot really see how this works, but
'nothing' could be 'no' (similar in meaning) and 'no' is found in the answer.
A single letter 't' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'there's' is the link.
Can you help me to learn more?
(Other definitions for not that I've seen before include "Negation of what follows" , "Word of denial" , "In no way, never" , "Having close-cut hair" , "Word of negation" .)
