Noun (source code)

= Noun

A <noun> is a <part of speech> whose members commonly name entities or concepts and head <noun phrases>. Meanings alone do not supply a complete classification: a <noun> can name an event or property as readily as a physical object. Distribution and <inflection> provide additional grammatical evidence.<Universal Dependencies annotation guidelines>[NOUN, Definition and examples including abstract nouns]{ref}

For example, `explosion` names an event, but behaves as a <noun> in `the explosion` and `two explosions`. Its connection with an event does not make it a <verb>; compare `The shell exploded`. Likewise, `redness` is a <noun> even though it names a property associated with the <adjective> `red`.

In <Universal Dependencies>, the tag `NOUN` is reserved for <common nouns>, with `PROPN` used for <proper nouns>. That distinction matters when reproducing an analysis: a count of every traditionally named noun is not necessarily a count of only tokens tagged `NOUN`.
