Language teaching and learning
The corpora are useful as reference sources in language teaching and learning, as supplements to dictionaries and grammar books; they provide teachers with samples of empirical language data that can be included in or adapted for teaching materials (e.g., vocabulary lists and cloze tests); they expose learners to authentic instances of language use, which can be particularly beneficial to those studying language for specific purposes (e.g., academic and business writing).
Linguistics and corpus linguistics research
The corpora are sources of raw data that can be used for research on various aspects of language and linguistics including lexical semantics, syntax, morphology, grammar, pragmatics, discourse, and second language acquisition.
Translation and translation studies
Texts from the comparable or parallel corpora can be compared and studied in order to identify suitable translation equivalents of terms; other monolingual, domain-specific corpora can also be utilised to create glossaries of domain-specific terms, which can be of practical use in translating and language learning.
