Symbolic identifier originally with a pointed shape (6)
I believe the answer is:
iconic
'symbolic' is the definition.
(I've seen this before)
'identifier originally with a pointed shape' is the wordplay.
'originally' suggests taking the first letters.
'with' means one lot of letters go next to another.
'a pointed shape' becomes 'conic' (conic is a kind of shape. I am not sure about the 'pointed' bit.).
The initial letter of 'identifier' is 'i'.
'i'+'conic'='ICONIC'
Can you help me to learn more?
(Other definitions for iconic that I've seen before include "Highly representative" , "Relating to religious pictures" , "Like a venerated image" , "Representatively symbolic" , "highly symbolic" .)
