Routine performer on top of sink? (3,6)
I believe the answer is:
tap dancer
This clue could be a double definition.
'routine performer' is the first definition.
'tap dancer' can be an answer for 'performer' (tap dancer is a kind of performer). I'm unsure of the 'routine' bit.
'top of sink?' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'on' is the link.
Can you help me to learn more?
(Other definitions for tap dancer that I've seen before include "Performer good on wooden stage" , "Astaire or Kelly, for example" , "Heel and toe clicker?" , "Hard shoe hoofer" , "One trips on hard floor" .)
