"decrement" should pass

[Ron-Lavi]

Looks like decrement is a valid English word, see also: https://dictionary.cambridge.org/dictionary/english/decrement

but I am still getting a warning about it with the plugin: You have a misspelled word: decrement on String spellcheck/spell-checker

[aotaduy]

I think we might have an outdated dictionary, you can use your own dictionary by using langDir option or, skip the word with a skipWord in the configuration
