A complete free Slovak course with exercises and a dictionary, EU-funded.
About this tool →Three levels of structured lessons with audio, exercises and grammar tables, plus a bilingual dictionary, available in a dozen interface languages and entirely free. It came out of an EU language project, which is why it exists at all — Slovak has very little commercial learner material.
Every official Slovak dictionary searched at once, from the Academy of Sciences.
About this tool →The Ľudovít Štúr Institute's portal queries the standard monolingual dictionaries, the orthographic rules and the historical dictionaries together. It is the authority on what is correct Slovak, which matters in a language whose standard is closely codified.
Free multilingual dictionary with etymologies, IPA and full conjugation tables.
About this tool →Over 100 language editions; the English edition alone has millions of entries covering hundreds of languages, with IPA, declension and conjugation tables, etymologies and usage notes that commercial apps usually paywall. The etymology sections are quietly one of the best vocabulary-retention tools available. Being crowd-sourced, coverage is uneven and rare entries can be wrong — cross-check anything unusual against a native-language dictionary.
Crowd-sourced pronunciations of nearly any word by native speakers.
About this tool →Around 6 million words recorded by native speakers across 400+ languages, usually with several accents per word so you can hear regional variation. Free to search on the site; the paid tiers are aimed at API users and bulk audio downloads. Indispensable for names, place names and anything a TTS voice would mangle — many learners wire it directly into Anki for card audio.
