Apt to be bent over the sink (3)
I believe the answer is:
tap
'bent over the sink' is the definition.
I can't judge whether this definition defines the answer.
'apt to be' is the wordplay.
'to be' is an anagram indicator.
'apt' anagrammed gives 'TAP'.
Can you help me to learn more?
(Other definitions for tap that I've seen before include "Gentle stroke" , "1dn to get on the phone, perhaps!" , "Obtain money from" , "A form of dance" , "Bugging device" .)
