The parting word that wishes well — a goodbye with warmth in it, never a ceremony before its hour.

To meet another with acknowledgment. A greeting says I see you before it says anything else.

To bring a thing into a room for the first time — arrival with a welcome attached.

Comes together with, or satisfies a standard. Both are about reaching something.

Welcome, in Icelandic. A greeting kept in its own tongue rather than translated.
