International event; international lingo (3)
I believe the answer is:
ido
'international lingo' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'international event' is the wordplay.
'international' becomes 'i' (abbreviation eg in IMF).
'event' becomes 'do' (do is a kind of event).
'i'+'do'='IDO'
Can you help me to learn more?
(Other definitions for ido that I've seen before include "Wedding response" , "Artificial language" , "Words made up" , "Wedding vow" , "See 1" .)
