DAFlex is a lexicon of receptive vocabulary for German as a second/foreign language that reports the normalized frequencies of words (lemmas) across the six levels of the CEFR (Common European Framework of Reference for Languages). The frequencies have been estimated on a corpus of textbooks and simplified readers.

bar_chart	CEFR levels A1 · A2 · B1 · B2 · C1 · C2
toc	Lexical entries lemma (word) part of speech (tag) · TreeTagger for German - Deutsches Wortart-Tagset (STTS)
