Number: number

Values: Coll Dual Plur Ptan Sing

Number is an inflectional feature of nouns and other parts of speech (adjectives, verbs) that mark agreement with nouns.

Sing: singular number

A singular noun denotes one person, animal or thing.


Plur: plural number

A plural noun denotes several persons, animals or things.


Dual: dual number

A dual noun denotes two objects. The dual number has almost vanished from Czech with the exception of special instrumental case suffixes for body parts that occur in pairs, and any adjectives that modify them.


The noun noha  means either “leg” of a human, or of a table. Dual is used for the former and plural for the latter:

The numeral sto  “hundred” has also a special form of plural that is actually the dual:

Ptan: plurale tantum

Some nouns appear only in the plural form even though they denote one thing (semantic singular); some tagsets mark this distinction. Grammatically they behave like plurals, so Plur is obviously the back-off value here; however, the non-existence of singular form sometimes means that the gender is unknown. In Czech, special type of numerals is used when counting nouns that are plurale tantum (NumType=Sets).


Coll: collective / mass / singulare tantum

Collective or mass or singulare tantum is a special case of singular. It applies to words that use grammatical singular to describe sets of objects, i.e. semantic plural. Although in theory they might be able to form plural, in practice it would be rarely semantically plausible. Sometimes, the plural form exists and means “several sorts of” or “several packages of”.



Prague Dependency Treebank

The PDT tagset does not distinguish Ptan from Plur and Coll from Sing, therefore this distinction is not being made in the converted data.
