Controlled Language Processing
Controlled language processing is a natural language processing approach in which computational systems analyze language that has been deliberately restricted in its vocabulary, syntax, and/or semantics according to explicitly defined rules [1]. It encompasses operations such as parsing controlled-language input into syntactic structures, deriving formal representations from those structures, and performing computational reasoning over the resulting representations [2]. It is distinct from unrestricted natural language processing in that the input language is intentionally constrained to support more predictable linguistic analysis and interpretation [1].

Colloquialism
A colloquialism is a word, phrase, or expression associated with informal language use, particularly everyday conversation, and distinguished from forms conventionally preferred in more formal contexts [1]. Colloquialisms are defined primarily by their register and conditions of use rather than by a particular grammatical structure or regional origin; they may occur in speech and informal writing. The term is related to, but not synonymous with, slang: slang commonly refers to a more socially marked subset of informal vocabulary, whereas colloquial usage is a broader category [1][2].

Classic Expression Grammar
In formal grammar and compiler theory, a classic expression grammar is a context-free grammar that specifies the syntactic structure of arithmetic expressions by separating expression components into grammatical categories corresponding to different operator-precedence levels [1]. In its conventional form, the grammar distinguishes expressions involving addition and subtraction, terms involving multiplication and division, and factors involving parenthesized expressions or operands. This hierarchical organization encodes operator precedence and, through recursive production rules, associativity, allowing expressions to be parsed into a structured representation without treating all operators as having equal precedence [1]. The term refers to a grammar used to describe expression syntax, rather than to a general theory of natural-language grammar.

Chinese Script Systems
Chinese script systems are writing systems that use Chinese characters and related graphic conventions to represent linguistic units in written language. The core Chinese writing system employs characters whose structures may combine semantic and phonetic components; the relationship between a character and spoken language is therefore not equivalent to a one-letter-to-one-sound correspondence in alphabetic writing [1]. The term can also encompass character-based systems adapted to represent other Sinitic varieties and non-Sinitic languages, as well as transcription and romanization systems used to represent Chinese speech through other scripts [1][2]. Within this broader category, traditional and simplified Chinese characters are graphic forms within the Chinese writing system, whereas romanization systems use alphabetic symbols and constitute a distinct means of representing Chinese pronunciation [2].

Ambiguity Theory
Ambiguity theory, within linguistics, refers to theoretical approaches that examine how linguistic expressions permit multiple interpretations and how those interpretations are represented, distinguished, and resolved during language comprehension [1]. Linguistic ambiguity may occur at lexical, morphological, syntactic, or pragmatic levels, depending on whether alternative interpretations arise from a word’s meanings, its morphological structure, the grammatical structure of an expression, or its interpretation in context [1]. The concept concerns the analysis and processing of multiple possible interpretations and is distinct from vagueness, in which an expression has an imprecise meaning rather than two or more clearly distinguishable interpretations [1].

Orality
Orality is the mode of language and communication in which spoken utterance is the primary medium for producing, transmitting, and interpreting verbal discourse, as distinct from written language, which relies on graphic representation [1]. In linguistic and cultural studies, the concept also refers to the communicative practices and discourse characteristics associated with spoken communication, including the roles of speaker, listener, interactional context, and performance in the organization and interpretation of verbal expression [1]. Orality is therefore distinct from literacy as a mode of communication, although oral and written practices may coexist and interact within the same social and cultural context [1].

Linguistic Identity Discourse
Linguistic identity discourse refers to the use and analysis of spoken, written, or other semiotic practices through which linguistic identities are expressed, constructed, negotiated, and interpreted in social contexts [1][2]. It encompasses discourse practices that position individuals or groups in relation to social categories and memberships, with identity treated not solely as a fixed attribute but also as an interactional and socially situated accomplishment [1]. The concept lies at the intersection of sociolinguistics and discourse analysis, focusing on how linguistic choices and discourse practices index, reproduce, or contest identities rather than treating linguistic identity as equivalent to language proficiency or language use alone [1][2].

Heritage Language
A heritage language is a language associated with an individual's family, ancestry, cultural identity, or community that differs from the dominant language of the broader social environment. The term encompasses languages acquired or encountered through familial or community contexts, as well as ancestral languages with which individuals maintain a cultural or personal connection, regardless of whether the language is regularly spoken at home or whether the individual has high proficiency in it [1]. The concept is context-dependent and does not require a uniform level of linguistic competence; it is distinct from a second language defined solely by the circumstances or sequence of its acquisition because heritage-language status also involves social, cultural, and biographical relationships to a language [1][2].

Cross-Cultural Pragmatics
Cross-cultural pragmatics is a field of pragmatics that examines how speakers from different cultural and linguistic backgrounds use and interpret language in context. It investigates how culturally shaped conventions, communicative expectations, and sociopragmatic norms influence the production and interpretation of speech acts, the expression of interpersonal relationships, and the management of interaction [1][2]. The field distinguishes differences in the linguistic forms used to perform communicative actions from differences in the social norms governing their appropriateness and interpretation, while examining how contextual and cultural knowledge contributes to pragmatic meaning [1][2]. It is related to intercultural communication but is specifically concerned with the pragmatic dimensions of language use and interpretation across cultural contexts.

Creole
A creole is a natural language that develops through sustained contact among speakers of different languages and becomes the first language of a speech community. In a commonly used sociolinguistic account, creole languages emerge when a contact language, often a pidgin, becomes nativized and develops into a language used as the community’s native language [1]. The classification of a language as a creole is based substantially on its sociohistorical development rather than on a single set of structural features, since creole languages possess systematic grammatical and phonological structures and cannot be defined solely by linguistic simplicity or complexity [1][2]. A creole is therefore distinct from a pidgin, which is conventionally characterized by its initial function as a contact language that is not the native language of a speech community, although the processes and pathways through which creoles emerge vary across linguistic contexts [1].
