Corpus linguistics is the study of language as expressed in corpora (samples) of "real world" text. The text-corpus method is a digestive approach for deriving a set of abstract rules, from a text, for governing a natural language, and how that language relates to and with another language; originally derived manually, coprora now are automatically derived from the source texts. Corpus linguistics proposes that reliable language analysis is more feasible with corpora collected in the field, in their natural contexts, and with minimal experimental-interference.
