The basic values of the number attribute are to be found in Table 5.2, "Values of the number grammateme".
The number grammateme is a tectogrammatical correlate of the morphological category of number. It is assigned to:
nodes of all (subgroups of) semantic nouns (see Section 6.1, "Semantic nouns").
With most semantic nouns, the value of the number grammateme corresponds to the value of the morphological number category; e.g.:
pes [number=sg] (=dog)
psi [number=pl] (=dogs)
Ti už nepřijdou. [number=pl] (=Those will not come any more)
The values are different in the cases of:
pluralia tantum.
The value of the number grammateme corresponds to the "quantity" of the denoted objects. For example:
jedny dveře [number=sg] (=one door)
dvoje dveře [number=pl] (=two doors)

using the polite form.
A node with the #PersPron t-lemma representing a second person pronoun has the sg value in its number grammateme if it refers to one person. For example:
Vy jste se nepřihlásil? [number=sg] (=lit. You.pl AUX not_registered.sg?)
For more details, see Section 6.1.3, "Definite pronominal semantic nouns: personal pronouns".
indefinite pronominal semantic nouns.
In case the indefinite pronominal semantic noun is the subject of a predicate in plural, the assigned value of its number grammateme is pl. For example:
Řekněte, kdo přišli. [number=pl] (=Tell us who came.pl)
These pronouns have a single set of forms, usually taken to be singular, which, however, often refer to more individuals (when the predicate is in plural).
For more details, see Section 6.1.4, "Indefinite pronominal semantic nouns".
The number grammateme of definite quantificational semantic nouns. The number grammateme of definite quantificational semantic nouns constitutes a specific issue. As for the cardinal numerals jeden (=one) through devětadevadesát (=ninety-nine), the value of their number grammateme follows from the lexical meaning of the semantic noun. For example:
Přišla jen jedna. [number=sg] (=lit. Came.sg.f only one)
Přišli dva. [number=pl] (=lit. Came.pl.m.anim two)
As for the numerals with the "container" meaning, i.e. the numerals sto, tisíc, milion (=hundred, thousand, million) etc., and fraction numerals, the number grammateme corresponds to the value of the morphological category. For example:
Přišlo sto studentů. [number=sg] (=One hundred students came)
Přišlo dvě stě studentů. [number=pl] (=Two hundred students came)
