'Water' is a noun but not a verb.

A. Yes

B. No

A noun names a person, place, thing, idea, quality, action, or state. However, “noun” isn’t a purely semantic category—it’s defined more by how it behaves in sentences than by its meaning. In grammar, nouns form a large, open word class whose members can serve as the subject of a clause, the object of a verb, or the object of a preposition.

Other parts of speech contrast with nouns: verbs express actions or states, adjectives express qualities, and adverbs often modify manner, time, or place. Historically, nouns have also been described by their inflections (e.g., case, number, gender), but these categories vary across languages, so such definitions are language-specific.

Example – “water”:

• As a noun: a clear liquid essential to life (e.g., “May I have a glass of water?”).
• As a verb: to supply water to plants (e.g., “Please water the garden.”).
  “Water” is a common noun and is lowercase unless it starts a sentence. A proper noun names a specific entity (e.g., Atlantic Ocean, Sofia, India) and is capitalized.
