What is CEDEL2?

CEDEL2 is a large linguistic corpus (database) that contains the written and spoken language produced by learners of Spanish as a second/foreign language (L2). It also contains data from native speakers of different languages.

This is the new version of CEDEL2 (version 3), Oct. 2025. It already incorporates the data from earlier versions (CEDEL2 v.1 and v.2). CEDEL2 (v3.0) currently amounts to a total of 6,560 participants and 1,504,430 words, which makes it one of the largest corpora of its kind.

CEDEL2 holds data from 15 subcorpora of learners of Spanish with different L1 backgrounds (where ‘L1’ means the learners’ mother tongue and ‘L2’ their foreign language). For comparative purposes, CEDEL2 also contains 13 subcorpora from native speakers of different L1s.

Note: subcorpora are listed decreasingly according to number of words.
