Diachronic Corpora: Corpora that are constructed for a linguistic account of language in time
commonly contain texts representing language use during different periods of the language under
investigation. Given the recent history of sound recording technologies, diachronic corpora
represent written language over time, for example, the Helsinki Diachronic Corpus of English
Texts (Rissanen et al., 1991).
Learner Corpora: Corpus use in the language classroom has found its place in teaching and
learning contexts. For example, the International Corpus of Learner English (ICLE) (Granger
2003) and as its sub-corpus Turkish International Corpus of Learner English (TICLE) (Kilimci
and Can 2009) have been a source of research in teaching contexts in recent years.
