Use this settings page to select custom spelling dictionaries, create your own dictionaries, add words, and thus expand the basic spellchecking support provided by PyCharm by default.
Use this tab to configure the dictionaries to be used for spellchecking.
This area displays the list of user-defined dictionary files, which can be any of the following:
The built-in project-level and application-level dictionaries, which you populate by manually saving words to them.
Plain text files with the DIC extension, containing words separated with a new line.
Hunspell dictionaries, comprise two plain text files commonly sharing the same name, for example, en_GB.dic and en_GB.aff. The DIC file contains a list of words together with the applicable modification rules. The AFF file list prefixes and suffixes regulated by a specific modification rule. Hunspell dictionaries can be easily obtained online, for example, here.
