Language typology is the study of how languages are classified based on their structural features.

Genetic typology is the study of how languages are related to each other, while typological typology is the study of how languages are classified based on their structural features.

The goal of language typology is to identify universal features of language that are common to all languages.

Some of the universal features of language that have been identified by typologists include the presence of nouns and verbs, a system of tense, a system of aspect, and a system of modality.

Some of the most common typological features that are used to classify languages include word order, case marking, verb agreement, noun class systems, tone systems, evidentiality, polysynthetic languages, isolating languages, and agglutinative languages.

A language resource is a tool or material that can be used to learn or teach a language, a collection of data about a language, or a software program that can be used to process language data.

Some examples of language resources include dictionaries, grammars, textbooks, corpora, lexicons, ontologies, machine translation systems, speech recognition systems, and natural language processing tools.

Language resources can be used to learn or teach a language, to conduct research on language, and to develop language technologies.

Some of the challenges associated with developing language resources include the lack of data for many languages, the difficulty of creating high-quality resources, and the cost of developing resources.

Some of the trends in language resource development include the increasing use of data-driven methods, the development of more user-friendly resources, and the increasing availability of resources for low-resource languages.

Language resources can help to document and preserve endangered languages, promote the use of endangered languages, and revitalize endangered languages.

Some of the challenges associated with using language resources for language preservation include the lack of resources for many endangered languages, the difficulty of creating high-quality resources for endangered languages, and the cost of developing resources for endangered languages.

Language resources can be used to create educational materials in endangered languages, develop media content in endangered languages, and create language apps and games in endangered languages.

Language resources can be used to create language learning materials for endangered languages, develop language assessment tools for endangered languages, and create language corpora for endangered languages.

Language resources can help to inform language policy decisions, implement language policies, and evaluate the effectiveness of language policies.
