Grammar

Null describes something that has no legal or binding force, or zero value in mathematics. In this sense, it functions as an adjective by describing the quality or state of having no value or effect. For example, 'a null contract' means a contract with no legal effect - the word null describes what kind of contract it is.

Noxious is an adjective meaning harmful, poisonous, or very unpleasant. Adjectives describe qualities or characteristics of nouns. For example, in 'noxious fumes,' the word noxious describes what kind of fumes they are - harmful or poisonous. It characterizes the noun it modifies.

Nude is an adjective meaning naked or without clothing. Adjectives describe the state or condition of nouns. For example, in 'nude figures' in art, the word nude describes the state of the figures - they are without clothing. It characterizes what condition the noun is in.

The word 'Number' is primarily a noun that refers to a mathematical concept, quantity, or symbol used to represent count or value. It can be used as a verb (to count), but as a standalone word without context, its most fundamental classification is a noun. The other options (conjunction, adjective, adverb, preposition) do not describe the primary grammatical function of 'number'.

The word 'Nor' is a coordinating conjunction used to introduce an alternative negative clause or to connect two negative ideas. It pairs with 'neither' to show that two negative statements are both true. It cannot be a verb, noun, adjective, or preposition - its grammatical function is exclusively as a conjunction that connects negative constructions.

The word 'Normal' is an adjective that describes something conforming to a standard, typical, or expected pattern. It modifies nouns by indicating what is usual, regular, or average. It cannot function as a verb, pronoun, adverb, or preposition in its standard form. When you say 'normal weather' or 'normal behavior,' you're using it as an adjective to describe the noun.

The word 'Nun' is a noun that refers to a female member of a religious community, typically in Christian traditions. It names a person and can serve as a subject or object in sentences. It cannot be a verb, adjective, or adverb - its sole grammatical function is as a noun identifying a specific religious role.

The word 'Numb' is an adjective that describes a lack of physical sensation or feeling. It modifies nouns or pronouns to indicate that something has lost sensation (e.g., 'numb fingers'). It cannot be a conjunction, noun, adverb, or preposition. When you say your fingers are numb, you're using 'numb' as an adjective to describe the condition of your fingers.

The past tense of 'build' is 'built,' which is an irregular verb. It does not follow the regular pattern of adding '-ed'. Instead, it changes form completely. 'Builded' and 'builted' are incorrect spellings - this verb cannot be regularized. 'Builder' is a noun referring to a person who builds, not a verb form. This irregular pattern is similar to other verbs like 'send/sent' or 'spend/spent'.

To nag is to annoy someone with persistent fault-finding, criticism, or urging. This is an action word describing what someone does, making it a verb. While nag can sometimes be used as a noun (a person who nags), its primary and most common usage is as a verb.

Nail is primarily a noun referring to a fingernail or toenail on the human body, or a metal fastener used in construction. While nail can be used as a verb (to fasten something), its most common and fundamental meaning is as a noun.

Narrow is primarily an adjective describing something of small width or limited extent. For example, a narrow road or narrow escape. While it can function as a verb (to narrow something), its most common usage is as an adjective describing a quality or state.

Nasal is an adjective relating to the nose or the sense of smell. It describes sounds (nasal voice), anatomical features (nasal cavity), or medical conditions (nasal congestion). The word is used to describe characteristics, not to name things or perform actions.

Nascent is an adjective describing something just coming into existence or just beginning to develop. It means emerging or budding. The word is used to describe the early stage of things like movements, ideas, or careers, not to name them or act upon them.

A nation is a country or a large group of people with a shared culture, language, or history. Nation is a noun because it names a thing - specifically, a political or cultural entity. The word doesn't describe qualities or perform actions; it identifies an existing entity.
