Calligraphy item in kind, in a novel (6,3)
I believe the answer is:
indian ink
'calligraphy item' is the definition.
The definition suggests a singular noun which matches the answer.
'in kind in a novel' is the wordplay.
'novel' indicates an anagram (letters in a new or novel order).
'kind'+'in'+'a'='kindina'
'kindina' anagrammed gives 'dianink'.
'in'+'dianink'='INDIAN INK'
Can you help me to learn more?
(Other definitions for indian ink that I've seen before include "Maybe part of squid" , "black pigment" , "Draw with this" , "Writing fluid containing carbon particles" , "Deep black writing fluid" .)
