Ctrl+Alt+S the Settings/Preferences icon

Use this settings page to select custom spelling dictionaries, create your own dictionaries, add words, and thus expand the basic spellchecking support provided by CLion by default.

Custom Dictionaries

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 lists prefixes and suffixes regulated by a specific modification rule. Hunspell dictionaries can be easily obtained online, for example, here.

note

Hunspell support is provided by the corresponding Hunspell plugin. The plugin is not bundled with CLion, but it can be installed on the Settings/Preferences | Plugins page, tab Marketplace, as described in Installing plugins from JetBrains repository.
