Change the word Categories

How can we change the word Categories? We mean just change the word, not the function. Where would I find thaT?

In which part of the theme you want to change this name? Could you please post your website URL where this word appears, so I can give you more accurate suggestions.

We want to change the word ‘Categories’ to ‘Archives by Category’. It is a widget in the right sidebar on all pages.

Thank you for your help.

You have changed widget title for other widgets and it’s the same for categories as well. Below I have attached screenshot from Appearances - Widgets section inside your WordPress dashboard.

Is this is what you were looking for?
