Brunette left Buster Keaton to relax in the bath (4)
I believe the answer is:
soak
'the bath' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'brunette left buster keaton to relax' is the wordplay.
'left' is a deletion indicator.
'to relax' indicates anagramming the letters (I've seen 'relaxes' mean this).
'buster'+'keaton'='busterkeaton'
'busterkeaton' with 'brunette' removed is 'skao'.
'skao' anagrammed gives 'SOAK'.
'in' is the link.
Can you help me to learn more?
(Other definitions for soak that I've seen before include "Immerse in liquid" , "Steep in water" , "Make thoroughly wet" , "Saturate" , "Habitual drinker (slang)" .)
