“usage,” like when to use “will” and when to use “shall” (“Will, in the first person singular and plural, promises or threatens; in the second and third persons, only foretells; shall on the contrary, in the first person, simply foretells; in the second and third persons, promises, commands, or threatens”)
I never thought either word imppied a threat. Huh..and it reverses in first and third person.
