we (Eng.): the plural of the first personal pronoun (the singular being ‘ego,’ ‘I’, q.v.); this pronoun refers to the speakers themselves; see nos; “It is frequently used instead of ego” (Lewis & Short), that is, an individual, such as an author or orator, in a text may refer to him or herself using this plural pronoun, rather than the singular, ‘ego;

        plural  
Nom. nos      (we)  
Gen. nostrum  (of us)  
     nostri   (of us)  
Dat. nobis    (to/for us)

- Mougeot et Nestler muscorum Vogesiacorum nos compotes fecerunt, Mougeot and Nestler made us [intellectual] masters of the mosses of [the Vogesian Mountains] [i.e. by the issuance of an exsiccate from this area]; nos = acc. pl.

- stamina ab auctoribus coalescentia dicuntur, nobis tamen libera apparent (B&H), the stamens by authors are called coalescent, yet by us they appear free.

NOTE: the genitives nostrum and nostri are not used to indicate possession. ‘Our’ is indicated using the possessive pronominal adjectives noster (m.), nostra (f.), nostrum (n.) (adj.A), q.v.

a. ‘nostrum’ was used only as partitive genitive (‘genitive of the whole’)

- magna pars nostrum, a great part of us.

- quis nostrum, who of us.

b. nostri was used only as an objective genitive;

- timor nostri, fear of us.

- caritate nostri pro vobis, with the affection of us for (all you).

NOTE: the nominatives of the personal pronouns were only used to stress the subject(s), otherwise, they were omitted and the pronoun is understood by the verbal endings: -mus;

- nos putamus numerus specierum Rutacearum parvior quam Rosacearum, we (ourselves) consider the number of species of the Rutaceae smaller than of the Rosaceae. ‘nos’ may be deleted and the subject is understood by the form of the verb ‘putamus, ‘we (pl.) consider.’

NOTE: ‘cum’ is a preposition used with the ablative case; when used with the pronoun ‘nobis’ (the ablative of ‘nos’), the preposition is joined to the end of the pronoun: nobiscum, ‘with us;’

- species nobiscum verae sunt, the species with us are true.

- specimina nobiscum curata, the specimens cared for by us.
