HI
Fiftieth state's letters
Hi is an informal greeting, slightly more casual than hello: Hi, how are you?
It works for strangers and friends alike but feels too relaxed for formal contexts.
Hi can also open written messages: Hi, just checking in. (Capitalized HI is the postal abbreviation for Hawaii.)
