On this page you will find the best online dictionaries. Some are downloadable. You can make use of GoldenDict to consort them.

Dictionaries listed must be digitalised and are able to be searched by text.

If a database is used by several dictionaries, only one will appear on the list, other popular ones are below the main list.

If a database on a website is from elsewhere, then this database will not be taken into consideration (except OneLook).

Computer programs will be added later.

In progress.

Main

Source languages are sub-headings, target languages are paragraph. “Searching by entry content” is excluded, i.e. only “searching by headword” is taken into consideration, in terms of “source languages” and “target languages”. This resembles the layout of the paper dictionary.

Websites with same database and unknown name are marked in parenthesis with the term “duplicated”.

Q&A

Q: How many words does it have?

A: Find some random words with different frequency levels (for example top 1000, 5000, 10000, 50000), according to the lists on Wiktionary or somewhere else. Then you can test it.

Q: How to evaluate it?

A: Find a random word and search in the dictionary, then ignore the headword, just see the entry and see how many headwords you can come up with. If you can always recall one word, that means the dictionary is very precise. If it's one-one projection, it may cause big misunderstandings because words are usually don't have exactly corresponding semes. Part-of-speech is essential. But being precise is not the only thing to care about. The entry should be brief, too. You shouldn't expect a hobbyist dictionary to reach this high quality, but a satisfying level.

Q: Can translators serve as dictionaries?

A: See if the translator returns multiple results. If it only return one result for a word, it can't meet your demand sometimes.

Q: What other aspects should I consider?

A: First, privacy and security. HTTP is less secure than HTTPS. If you have uMatrix installed, you can see how many third-parties a website contains. For apps, check their permissions. Second, see if it is licensed under any public copyright license. This kind of license makes sure that anyone can access it and do something with it without worry about copyright matters, so it can be easily reproduced and wide spreaded. Third, see if it is actively updated. A discontinued dictionary may contain more mistakes. An important factor for an actively updated dictionary is a community, which may be guaranteed by public copyright licenses.
