Linguistic in the context of "Sangam era"

Choronym (from Greek: χώρα 'region' or 'country' and Greek: ὄνομα 'name') is a linguistic term that designates a proper name of an individual region or a country. The study of regional and country names is known as choronymy, or choronymics. Since choronyms are a subclass of toponyms, choronymic studies represent a distinctive subfield of toponymic studies and belong to the wider field of onomastic studies.

Choronymic studies are primarily focused on questions related to the origin (etymology) and meanings (semantics) of choronyms. Since names of regions and countries have great historical, cultural, political and social significance, the field of choronymic studies is closely related to sociolinguistic and ethnolinguistic studies.

Asemic writing is a wordless open semantic form of writing. The word asemic /eɪˈsiːmɪk/ means "having no specific semantic content", or "without the smallest unit of meaning". Asemic writing fuses text and image together, while minimising the use of gestures, lines and symbols. Its non-specificity leaves readers to interpret its meaning – such works can have multiple meanings that evolve over time. The open nature of asemic works allows for meaning to occur across linguistic understanding; an asemic text may be "read" in a similar fashion regardless of the reader's natural language.

Propositions are the meanings of declarative sentences, objects of beliefs, and bearers of truth values. They explain how different sentences, like the English "Snow is white" and the German "Schnee ist weiß", can have identical meaning by expressing the same proposition. Similarly, they ground the fact that different people can share a belief by being directed at the same content. True propositions describe the world as it is, while false ones fail to do so. Researchers distinguish types of propositions by their informational content and mode of assertion, such as the contrasts between affirmative and negative propositions, between universal and existential propositions, and between categorical and conditional propositions.

Many theories of the nature and roles of propositions have been proposed. Realists argue that propositions form part of reality, a view rejected by anti-realists. Non-reductive realists understand propositions as a unique kind of entity, whereas reductive realists analyze them in terms of other entities. One proposal sees them as sets of possible worlds, reflecting the idea that understanding a proposition involves grasping the circumstances under which it would be true. A different suggestion focuses on the individuals and concepts to which a proposition refers, defining propositions as structured entities composed of these constituents. Other accounts characterize propositions as specific kinds of properties, relations, or states of affairs. Philosophers also debate whether propositions are abstract objects outside space and time, psychological entities dependent on mental activity, or linguistic entities grounded in language. Paradoxes challenge the different theories of propositions, such as the liar's paradox. The study of propositions has its roots in ancient philosophy, with influential contributions from Aristotle and the Stoics, and later from William of Ockham, Gottlob Frege, and Bertrand Russell.

Linguistic purism or linguistic protectionism is a concept with two common meanings: one with respect to foreign languages and the other with respect to the internal variants of a language (dialects).The first meaning is the historical trend of the users of a language desiring to conserve intact the language's lexical structure of word families, in opposition to foreign influence which are considered 'impure'. The second meaning is the prescriptive practice of determining and recognizing one linguistic variety (dialect) as being purer or of intrinsically higher quality than other related varieties.

The perceived or actual decline identified by the purists may take the form of a change of vocabulary, syncretism of grammatical elements, or loanwords. The unwanted similarity is often with a neighboring language the speakers of which are culturally or politically dominant. The ideal may invoke logic, clarity, or the grammar of classic languages. It is often presented as a conservative measure, as a protection of a language from the encroachment of other languages or of the conservation of the national Volksgeist, but is often innovative in defining a new standard. It is sometimes part of governmental language policy that is enforced in various ways.

Formal semantics is the scientific study of linguistic meaning through formal tools from logic and mathematics. It is an interdisciplinary field, sometimes regarded as a subfield of both linguistics and philosophy of language. Formal semanticists rely on diverse methods to analyze natural language. Many examine the meaning of a sentence by studying the circumstances in which it would be true. They describe these circumstances using abstract mathematical models to represent entities and their features. The principle of compositionality helps them link the meaning of expressions to abstract objects in these models. This principle asserts that the meaning of a compound expression is determined by the meanings of its parts.

Propositional and predicate logic are formal systems used to analyze the semantic structure of sentences. They introduce concepts like singular terms, predicates, quantifiers, and logical connectives to represent the logical form of natural language expressions. Type theory is another approach utilized to describe sentences as nested functions with precisely defined input and output types. Various theoretical frameworks build on these systems. Possible world semantics and situation semantics evaluate truth across different hypothetical scenarios. Dynamic semantics analyzes the meaning of a sentence as the information contribution it makes.

A personal name, full name or prosoponym (from Ancient Greek prósōpon – person, and onoma –name) is the set of names by which an individual person or animal is known. When taken together as a phrase, they all relate to that one individual. In many cultures, the term is synonymous with the birth name or legal name of the individual. In linguistic classification, personal names are studied within a specific onomastic discipline, called anthroponymy.

In Western culture, nearly all individuals possess at least one given name (also known as a first name, forename, or Christian name), together with a surname (also known as a last name or family name). In the name "James Smith", for example, James is the first name and Smith is the surname. Surnames in the West generally indicate that the individual belongs to a family, a tribe, or a clan, although the exact relationships vary: they may be given at birth, taken upon adoption, changed upon marriage, and so on. Where there are two or more given names, typically only one (in English-speaking cultures usually the first) is used in normal speech.
