Parable I utilised in original way to convey meaning primarily (10)
I believe the answer is:
similitude
'parable' is the definition.
(thesaurus)
'utilised in original way to convey meaning primarily' is the wordplay.
'original' indicates taking the first letters (the origin of the word).
'way' indicates an anagram (another way of arranging the letters).
'to convey' indicates putting letters inside (convey can mean to carry).
'primarily' indicates taking the first letters.
The first letter of 'in' is 'i'.
The first letter of 'meaning' is 'm'.
'utilised'+'i'='utilisedi'
'utilisedi' anagrammed gives 'siilitude'.
'siilitude' going around 'm' is 'SIMILITUDE'.
'i' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for similitude that I've seen before include "Nearly identical quality" , "Correspondence" .)
