Comprehensive English dictionary, containing English words, phrases, definitions, synonyms and terms. The main page features a few definitions, but there’s also a search feature implemented on the website.
Each term is explained thoroughly, has its own pronunciation explained and other related words. A couple of derivations of the word are also available and explained as well.
While it’s true that it provides basically the same functions as any other English online dictionary, this website is ads and spam-free. A total of three sources are used to complete the definitions: WordNet, Oxford English Dictionary 1884, and Websters Dictionary 1913.
