Linguistic Universals are the common features and patterns that are found across different languages, regardless of their geographical or cultural origins.

Historical constraints are not typically considered to be a major factor in explaining linguistic universals, as languages can change and evolve over time, leading to differences between languages.

Language Convergence is the process by which languages that are in close geographical proximity tend to develop similar features and structures over time, due to factors such as trade, migration, and cultural exchange.

Calque is not a mechanism for language convergence, as it refers to the process of creating new words or phrases in one language by directly translating them from another language, rather than borrowing them.

Language Divergence is the process by which languages that are spoken by different social groups within a society tend to develop different features and structures over time, due to factors such as social stratification, isolation, and cultural differences.

Language Contact is not a mechanism for language divergence, as it refers to the process of interaction between two or more languages, which can lead to language convergence or language change.

A Global Language is a language that is spoken by a large number of people across different regions and cultures, and is often used for international communication and trade.

Technological Advancements are not typically considered to be a major factor in explaining the rise of global languages, as they can facilitate communication between people who speak different languages, but do not necessarily lead to the dominance of a single language.

An Official Language is a language that is used for official purposes, such as government, education, and media, within a particular country or region.

Economic Factors are not typically considered to be a major factor in explaining the choice of official languages, as they are more likely to influence the choice of a lingua franca or global language.

A Minority Language is a language that is spoken by a small number of people, often within a specific geographical area or community.

Language Contact is not typically considered to be a major factor in explaining the endangerment of minority languages, as it can sometimes lead to language revitalization or language maintenance.

An Extinct Language is a language that is no longer spoken by any living speakers.

Language Contact is not typically considered to be a major factor in explaining language extinction, as it can sometimes lead to language revitalization or language maintenance.

Language Revitalization is the process of reviving or revitalizing a language after a period of decline or dormancy.
