Hail is a noun referring to precipitation in the form of spherical pellets of ice, and it’s a verb meaning (1) to salute or greet, (2) to call out in order to catch the attention of, and (3) to come or originate from. The precipitation-related sense can also be used as a verb. Hale usually means free from infirmity or illness, but it also has a rarer verb sense—to compel to go (usually to court).
