Rarely it could be associated with writing (8)
I believe the answer is:
literary
'associated with writing' is the definition.
I can't tell whether this defines the answer.
'rarely it could be' is the wordplay.
'could be' is an anagram indicator.
'rarely'+'it'='rarelyit'
'rarelyit' is an anagram of 'LITERARY'.
Can you help me to learn more?
(Other definitions for literary that I've seen before include "well read" , "Concerning writing of artistic value" , "To do with books, poems etc" , "Associated with formal writing" , "Type of writing of artistic merit" .)
