256. The "second" and "third" persons of the imperative are used to
express peremptory commands and prohibitions.
a. In the second person the pronoun is usually omitted, as in English,
unless special emphasis is placed upon it:
Estu trankvila! Be calm! (One person is addressed.)
Estu pretaj por akompani min!
Be ready to accompany me! (Two or more persons are addressed.)
Parolu kvazaux vi komprenus! Talk as though you understood!
Ne fermu tiun pordon! Do not shut that door!
Ne estu vidata tie! Do not be seen there!
b. In the third person a circumlocution in English is necessary in
translation (as "let", "must", "are to", "is to", etc.):
Li estu zorga! Let him be careful (he must be careful)!
Sxi ne faru tion! Do not let her do that (she is not to do that)!
Cxio estu pardonata! Let everything be forgiven!
Oni lasu min trankvila! People are to let me alone!
Ili neniam revenu! Let them never (do not let them ever) return!
La kulpuloj estu punataj! Let the culprits be punished!
