Strangely hot drink losing temperature left inside (5)
I believe the answer is:
oddly
'strangely' is the definition.
(I know that strangely can be written as oddly)
'hot drink losing temperature left inside' is the wordplay.
I cannot quite understand how this works, but
'left' could be 'odd' (synonyms) and 'odd' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for oddly that I've seen before include "Unusually" , "In a strange way" , "This clue [32A] is not numbered so" , "strange to say?" , "In a peculiar way" .)
