Ondrej Holzman The new Dictionaries application should not be missed by anyone who uses a Mac and does not yet have a Czech translation dictionary or spell checker installed on it. Václav Slavík prepared a tool that makes adding these two useful elements very easy.
Dictionaries support a total of 44 languages, including Czech. If you add it via the Mac application, you will get both a translation dictionary (from Czech to English and vice versa) and also a spell checker. Application data is collected from Wiktionary and the Czech language alone offers over 44 passwords, in addition, the developer promises to update the database regularly.
The advantage of dictionaries in Dictionaries is not only in easy installation, when you just have to choose the desired language from the menu and click once, but at the same time all dictionaries are formatted in OS X El Capitan style. So as soon as you look up a definition in the Dictionary system application or directly in various applications, everything fits together. A detail that, however, may have bothered some users with other dictionaries.
At the same time, Dictionaries will also install a spell checker in the selected language on the Mac, which almost every user will use. The same "spellchecker" installed by Dictionaries is also used by OpenOffice or Firefox, so the database is of good quality and the spell checker works well. For better functioning, it is good to set the Czech language System Preferences > Keyboard > Text > Spelling, however, OS X should recognize Czech after a while even in the case of automatic settings according to the language.
You can use the Dictionaries app download from Dictionaries.io for free, however you will get part of the dictionary passwords. The complete dictionary database can be unlocked for 6 euros (160 crowns), which is really a lot for how much work and time the built-in Czech spelling correction or explanatory dictionary can save.
Thank you for the tip. ? I will try.
More comprehensive and free. Adding to the system dictionary. It's not a click away, but it's worth it.

It still works on MacOS BigSur (11.3) and it's great. Thanks!
