Fit cap of tiny brown liquor bottle (7)
I believe the answer is:
tantrum
'fit' is the definition.
(synonyms)
'cap of tiny brown liquor bottle' is the wordplay.
I cannot quite understand how this works, but
'brown' could be 'tan' (tan is a kind of brown) and 'tan' is present in the answer.
'liquor' could be 'rum' (rum is a kind of liquor) and 'rum' is located in the answer.
A single letter 't' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tantrum that I've seen before include "Uncontrolled outburst of anger" , "throwing this?" , "Childish fit of anger" , "Childish angry outburst" , "Paddy" .)
