“acceuil” word in french version

Hello

In the different pages of my site, I have a section, in the upper part with the name of the page on the left and the folder tree on the rigth.
The root of this folder tree is “Acceuil” which is bad spelling of “Accueil”.
I didn’t find a way to change it in the wordpress API.
I have located this term in the \\wordpress\wp-content\languages\themes\suffice-fr_FR.mo file, but I’m a bit afraid of messing everything up by changing it.
I would rather have a clean way.
Thank you
