Using rag as well for ink (6)
I believe the answer is:
tattoo
'for ink' is the definition.
(I've seen this in another clue)
'using rag as well' is the wordplay.
I cannot quite understand how this works, but
'rag' could be 'tat' and 'tat' is found in the answer.
'as well' could be 'too' (both can mean 'also') and 'too' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tattoo that I've seen before include "hide design?" , "Personal design" , "Indelible impression" , "Military pageant" , "Design marked on skin" .)
