Sponge outline from designer tattooist (7)
I believe the answer is:
drinker
'sponge outline' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'designer tattooist' is the wordplay.
'designer' becomes 'dr' (I can't justify this - if you can you should believe this answer much more).
'tattooist' becomes 'inker'.
'dr'+'inker'='DRINKER'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for drinker that I've seen before include "Imbiber, toper" , "Consumer of liquid, probably alcohol" , "Inebriate" , "Tippler" .)
