Why aren't words starting with capitals corrected mid-sentence?

By default, the style lexicons in your linguistic preferences are turned on.

MerciApp treats words starting with a capital letter mid-sentence as proper nouns: think city names, people, brands, and so on. That's why they won't get flagged during correction.

This default behavior is actually there to help you: it prevents proper nouns from showing up as "unknown words" and can even suggest the right spelling for them.

Example:

The Véolia logo has just been changed > The Veolia logo has just been changed

Enable correction for capitalized words

Want MerciApp to correct all words starting with a capital mid-sentence? You can easily change that! Here's how:

Step 1: Head to your linguistic preferences

Go to your MerciApp space: https://web.merci-app.com/
Select Linguistic Preferences in the Correct section
Under the Style tab, uncheck all 4 lexicon preferences

Step 2: Adjust the new preference

Switch to the Spelling tab
Look for the option: "Ignore words whose first letter is capitalized (except at the start of a sentence)"
Uncheck it if you want every capitalized word to be corrected

Good to know before you change this

Upsides of turning it off:

Every word starting with a capital gets detected and corrected
You get more granular control over your corrections

One important downside:

MerciApp will flag all capitalized words including proper nouns like city names, people, and brands that naturally use capitals
MerciApp will no longer suggest corrections for proper nouns
