LEO Dictionary review
A feature-rich free dictionary for European-language learners who study online.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
LEO Dictionary is an online multilingual dictionary service for people learning European languages, with web, iOS and Android access. Its free lookup covers 12 language pairs, including English–German, French–German, Spanish–German and English–Spanish. Results can combine translations with definitions, grammar, etymology, noun and verb inflection tables, natural-voice pronunciation audio, examples and related contextual information. Users can also search phrases, idioms and complete text, making LEO useful for learners who need more than a basic word translation.
Its strongest area is the connection between dictionary lookup and vocabulary practice. Personal vocabulary lists, a vocabulary trainer and spaced-repetition practice support ongoing study, while language-learning forums add access to related discussions. Some vocabulary-trainer functions work offline, but the dictionary content itself remains online-only and cannot be downloaded. That makes LEO more suitable for connected study than for reference while travelling without internet access.
LEO offers a Free plan alongside LEO Pur annual and LEO Pur monthly plans. The published product details identify the plan structure but do not define the additional features for each paid tier. Learners who want pronunciation, usage examples, inflections and built-in vocabulary practice should find the free service well aligned with language study. Those who need downloadable dictionary content or fully offline lookup should choose an alternative with offline dictionaries instead.
