Non-drinker getting round in? Whisky? (3)

Ross

I believe the answer is:

tot

I'm a little stuck... Click here to teach me more about this clue!

'in? whisky?' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.

'non-drinker getting round' is the wordplay.
'non drinker' becomes 'tt' (Teetotaller abbreviation).
'getting' is an insertion indicator.
'round' becomes 'o' (round can mean a round object).
'tt' placed around 'o' is 'TOT'.

Can you help me to learn more?

(Other definitions for tot that I've seen before include "Small baby" , "Add up like infant" , "Small measure for a small child" , "Child; measure of spirits" , "Palindrome for small child" .)
