I would love to create artificial language (3)
I believe the answer is:
ido
'artificial language' is the definition.
(Ido is an example)
'i would love' is the wordplay.
'i would' becomes 'I'd'.
'love' becomes 'o' (love means zero in tennis).
'id'+'o'='IDO'
'to create' is the link.
(Other definitions for ido that I've seen before include "Words made up" , "Artificial language" , "Traditional affirmation to some marriage vows" , "Prepared tongue" , "Marriage response" .)
