What it actually is

The Czech National Corpus lets you search vast bodies of written and spoken Czech and see every attested context for a word or construction — the way to settle which preposition or case a verb really takes when dictionaries disagree or say nothing. Access is free but requires registration, and the query interfaces (KonText, SyD, Treq) are built for linguists, so there is a real learning curve. Overkill below B2; close to indispensable for anyone writing serious Czech.
