The hot toddy man (4)
I believe the answer is:
otto
'man' is the definition.
(I have seen 'A man' mean 'otto' so perhaps 'man' could also mean 'otto')
'the hot toddy' is the wordplay.
'OTTO' is hidden within the letters.
However, I am uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for otto that I've seen before include "Palindromic fragrance" , "Emperor's" , "fragrance comes from?" , "- - Preminger (films)" , "Essential oil from flowers - German boy's name" .)
