Almost leave in state of trembling (7)
I believe the answer is:
aquiver
'trembling' is the definition.
(I've seen this before)
'almost leave in state' is the wordplay.
I cannot quite understand how this works, but
'state' could be 'quiver' (quiver is a kind of state) and 'quiver' is found within the answer.
A single letter 'a' 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).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for aquiver that I've seen before include "far from steady" , "shaking" , "Flickering" , "shuddering" , "Trembling" .)
