Bona vortaro
• Each example followed by its source; links to Wikipedia and Reta Vortaro (↗).
• Icons for the fields.
• With many examples, the first one shows; the others with a tap.
• French and English search: "maison → domo".
• Reta Vortaro updated (October 2026).
• Search in Esperanto and in your other languages, with or without accents (cx → ĉ), and with wildcards (*ologio).
• Read clear articles: definitions, examples, remarks, links between words, and the translations in your languages, the examples' too.
• See which words are official (Fundamento, Official Additions), and browse the list of each Addition.
• Long-press a word to look it up, whatever its form: "arbojn" finds "arbo".
• Meet a word that isn't in the dictionary? The search suggests the roots and affixes it may be built from: "malsanulejestrano" = malsanulej + estr + ano.
• More French translations: thousands of French words that Reta Vortaro lacks, from the French Wiktionary, with a dotted underline in the articles.
• Definitions from the Esperanto Wiktionary for hundreds of words that Reta Vortaro lacks.
• After each example, the work it comes from; icons for the fields.
• Leaf through the dictionary from root to root, or discover a random root.
• Your recent searches, day and night colours, text size.
The app's interface is in Esperanto. You can search, and read the translations, in any of the dictionary's 170+ languages.
The name is a tribute to "La bona lingvo" by Claude Piron. Bona vortaro is based on PReVo by Neil Roberts.
