We didn’t recommend to edit the theme code without any major issue. Because it can crash the theme because of wrong editing of the code or a simple code related mistake.
Moreover, if you edit something from the theme code then you will be lost those customizations after installing an update of the theme. As we can see previously you had a lot of related questions/topics (here https://www.themelooks.com/support/forums/users/mike/topics/ ) and you may lose those customizations after installing an update of the theme.
So, we are recommending you to use the Loco Translate plugin for this simple translation issue.
