Stirring small amount in mug at last (8)
I believe the answer is:
touching
'stirring' is the definition.
('touch' can be a synonym of 'stir')
'small amount in mug at last' is the wordplay.
I cannot quite see how this works, but
'amount' could be 'touch' (touch is a kind of amount) and 'touch' is found in the answer.
'in' is within the answer.
A single letter 'g' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for touching that I've seen before include "Pathetic" , "feeling" , "Contiguous" , "Arousing feelings of sympathy or gratitude" , "Moving; in contact" .)
