hortatives
Hortatives are statements that urge or encourage action, often expressing inclusive exhortation for a group to act. In linguistic terms, hortative mood or hortative constructions convey a wish or command about collective action, usually in the first-person plural.

English commonly expresses hortatives with the particle let, especially in the form Let us ...: “Let us
Function and usage: hortatives express solidarity and motivate collective action, often in formal, religious, or ceremonial
