Welcome to the English-language Wiktionary, a collaborative project to produce a free-content multilingual dictionary. It aims to describe all words of all languages using definitions and descriptions in English.
Wiktionary has grown beyond a standard dictionary and now includes a thesaurus, a rhyme guide, phrase books, language statistics and extensive appendices. We aim to include not only the definition of a word, but also enough information to really understand it. Thus etymologies, pronunciations, sample quotations, synonyms, antonyms and translations are included.
Today is the International Day of the Tropics, which is recognized by the United Nations to highlight the important role that countries in tropicalareas of the world play in achieving the UN’s Sustainable Development Goals, and to raise awareness about the challenges faced by these areas. The first State of the Tropics Report by twelve tropical research institutions was launched on this day ten years ago in 2014.
This is the English-language Wiktionary, where words from all languages are defined in English. For example, see the entry for the French word dictionnaire. To find a French definition of that word, visit the equivalent page in the French Wiktionary.
