Type of cat embodied by Tantomile (3)
I believe the answer is:
tom
'type of cat' is the definition.
(I've seen this in another clue)
'embodied by tantomile' is the wordplay.
'embodied by' indicates a hidden word.
'TOM' can be found hidden inside 'tantomile'.
(Other definitions for tom that I've seen before include "Repeated twice, this becomes an African drum" , "Male beast" , "He is associated with Dick and Harry" , "Boy running off with pig" , "Edgar's Poor disguise (Lear)" .)
