Noun phrase in the context of Prepositional phrase

In contemporary literary studies, a theme is a main topic, subject, or message within a narrative. Themes are ideas that are central to a story, which can often be summed in a single abstract noun (for example, love, death, betrayal, nostalgia, or parenthood) or noun phrase (for example, coming of age, humans in conflict with technology, seeking spirituality in the modern era, or the dangers of unchecked ambition). A theme may be exemplified by the actions, utterances, or thoughts of characters, as in the theme of loneliness in John Steinbeck's Of Mice and Men, wherein many of the characters seem isolated and long for community with others. It may or may not differ from the thesis—the text's or author's implied worldview.

A story may have several themes and generally longer works, such as novels, plays, films, or television series, do. Themes often explore historically common or cross-culturally recognizable ideas, such as ethical questions, and are usually implied rather than stated explicitly. An example of this would be whether one should live a seemingly better life, at the price of giving up parts of one's humanity, which is a theme in Aldous Huxley's Brave New World. Along with plot, character, setting, and style, theme is considered one of the components of fiction. Themes can be divided into two categories: a work's thematic concept is what readers "think the work is about" and its thematic statement being "what the work says about the subject".

In linguistics, definiteness is a semantic feature of noun phrases that distinguishes between referents or senses that are identifiable in a given context (definite noun phrases) and those that are not (indefinite noun phrases). The prototypical definite noun phrase picks out a unique, familiar, specific referent such as the sun or Australia, as opposed to indefinite examples like an idea or some fish.

There is considerable variation in the expression of definiteness across languages, and some languages such as Japanese do not generally mark it, so the same expression can be definite in some contexts and indefinite in others. In other languages, such as English, it is usually marked by the selection of determiner (e.g., the vs. a). Still other languages, such as Danish, mark definiteness morphologically by changing the noun itself (e.g. Danish en mand (a man), manden (the man)).

An adjective (abbreviated ADJ) is a word that describes or defines a noun or noun phrase. Its semantic role is to change information given by the noun.The adjective is considered one of the main parts of speech of the English language, although historically they were classed together with nouns. Nowadays, certain words that usually had been classified as adjectives, including the, this, my, etc., typically are classed separately, as determiners.

In grammar, a phrase—called an expression in some contexts—is a group of one or more words acting as a grammatical unit. For instance, the English expression "the very happy squirrel" is a noun phrase which contains the adjective phrase "very happy". Phrases can consist of a single word or a complete sentence. In theoretical linguistics, phrases are often analyzed as units of syntactic structure such as a constituent. There is a difference between the common use of the term phrase and its technical use in linguistics. In common usage, a phrase is usually a group of words with some special idiomatic meaning or other significance, such as "all rights reserved", "economical with the truth", or "kick the bucket". It may be a euphemism, a saying or proverb, a fixed expression, a figure of speech, etc. In linguistics, these are known as phrasemes.

In theories of syntax, a phrase is any group of words, or sometimes a single word, which plays a particular role within the syntactic structure of a sentence. It does not have to have any special meaning or significance, or even exist anywhere outside of the sentence being analyzed, but it must function there as a complete grammatical unit. For example, in the sentence Yesterday I saw an orange bird with a white neck, the words an orange bird with a white neck form a noun phrase, or a determiner phrase in some theories, which functions as the object of the sentence.

In mathematics, an expression is an arrangement of symbols following the context-dependent, syntactic conventions of mathematical notation. Symbols can denote numbers, variables, operations, and functions. Other symbols include punctuation marks and brackets, used for grouping where there is not a well-defined order of operations.

Expressions are commonly distinguished from formulas: expressions usually denote mathematical objects, whereas formulas are statements about mathematical objects. This is analogous to natural language, where a noun phrase refers to an object, and a whole sentence refers to a fact. For example, ${\displaystyle 8x-5}$ and ${\displaystyle 3}$ are both expressions, while the inequality ${\displaystyle 8x-5\geq 3}$ is a formula. However, formulas are often considered as expressions that can be evaluated to the Boolean values true or false.

In linguistics and grammar, a pronoun (glossed PRO) is a word or a group of words that one may substitute for a noun or noun phrase.

Pronouns have traditionally been regarded as one of the parts of speech, but some modern theorists would not consider them to form a single class, in view of the variety of functions they perform cross-linguistically. An example of a pronoun is "you", which can be either singular or plural. Sub-types include personal and possessive pronouns, reflexive and reciprocal pronouns, demonstrative pronouns, relative and interrogative pronouns, and indefinite pronouns.

In linguistics, specificity is a semantic feature of noun phrases (NPs) that distinguishes between entities/nouns/referents that are unique in a given context and those that are not. Several distinct known factors determine an entity/noun/referent's relative specificity, including:

• Singular terms (e.g. proper names)
• Habituality
• Actual/Nonactual moods
• Factivity
• Negation

Specificity does not rely on existence. This is because specificity relies on the uniqueness of an entity, regardless of whether it may or may not actually exist. For example, “I’m looking for a male sister” refers to no actual entity. However, the ambiguity of its specificity (are you looking for a particular male sister, or any male sister?) is retained.

In grammar, a noun adjunct, attributive noun, qualifying noun, noun (pre)modifier, or apposite noun is an optional noun that modifies another noun; functioning similarly to an adjective, it is, more specifically, a noun functioning as a pre-modifier in a noun phrase. For example, in the phrase "chicken soup" the noun adjunct "chicken" modifies the noun "soup". It is irrelevant whether the resulting compound noun is spelled in one or two parts. "Field" is a noun adjunct in both "field player" and "fieldhouse".

In linguistics, the head or nucleus of a phrase is the word that determines the syntactic category of that phrase. For example, the head of the noun phrase "boiling hot water" is the noun (head noun) "water".

Analogously, the head of a compound is the stem that determines the semantic category of that compound. For example, the head of the compound noun "handbag" is "bag", since a handbag is a bag, not a hand.

Adpositions are a class of words used to express spatial or temporal relations (in, under, towards, behind, ago, etc.) or mark various semantic roles (of, for). The most common adpositions are prepositions (which precede their complement) and postpositions (which follow their complement).

An adposition typically combines with a noun phrase, this being called its complement, or sometimes object. English generally has prepositions rather than postpositions – words such as in, under and of precede their objects, such as "in England", "under the table", "of Jane" – although there are a few exceptions including ago and notwithstanding, as in "three days ago" and "financial limitations notwithstanding". Some languages that use a different word order have postpositions instead (like Turkic languages) or have both types (like Finnish). The phrase formed by an adposition together with its complement is called an adpositional phrase (or prepositional phrase, postpositional phrase, etc.). Such a phrase can function as a grammatical modifier or complement in a wide range of types of phrases.

In mathematical logic, a term is an arrangement of dependent/bound symbols that denotes a mathematical object within an expression/formula. In particular, terms appear as components of a formula. This is analogous to natural language, where a noun phrase refers to an object and a whole sentence refers to a fact.

A first-order term is recursively constructed from constant symbols, variable symbols, and function symbols.An expression formed by applying a predicate symbol to an appropriate number of terms is called an atomic formula, which evaluates to true or false in bivalent logics, given an interpretation.For example, ⁠${\displaystyle (x+1)*(x+1)}$⁠ is a term built from the constant 1, the variable x, and the binary function symbols ⁠${\displaystyle +}$⁠ and ⁠${\displaystyle *}$⁠; it is part of the atomic formula ⁠${\displaystyle (x+1)*(x+1)\geq 0}$⁠ which evaluates to true for each real-numbered value of x.

In grammar, the ergative case (abbreviated erg) is the grammatical case that identifies a nominal phrase as the agent of a transitive verb in ergative–absolutive languages.
