sendito

A sendito is a sent one, and the word says so. Send- is the verb, -it- is the passive past participle - the thing has been done to him, he has been sent - and -o turns the participle into a person. This is the participial nominal at its plainest, the same machine that gives amato a beloved, kondamnito a convict and konato an acquaintance. Learn to read -into, -anto and -ito as three different people and a whole shelf of vocabulary opens at once: a sendanto is the one doing the sending, a sendinto the one who did it, a sendito the one who was sent.

Not a delegito. The two are built identically and mean different things. A delegito is chosen by a body to represent it and carries its authority - a congress delegate, a union delegate. A sendito is simply somebody's sent man: a messenger, a courier, an emissary with an errand. One is a mandate, the other an errand.

In diplomacy it is a rank, not a synonym. An ambasadoro heads a mission; a sendito is the lower grade below him, what English called an envoy in the days when the distinction was worth arguing over. For ordinary sentences the ordinary sense is safe, and if you want the neutral word for the man with the message, kuriero is waiting.
