Do you mean the day part in n days ago in the tweet output?
That is a part of the output returned by the WordPress core function _n().
Try changing your site language via Dashboard -> Settings -> General -> Site Language (WordPress v4.0 or above) If you are WordPress version is below v4.0, you would need to edit the wp-config.php file and modify the line defining the language, which looks like
define( 'WPLANG', '...' );
Hope it helps.
Hello.
I tried via dashboard but didn’t change language. Any way to do that by editing some file?
Regards

The _n() is in my language, but not the “ago”. So I get “1 semana” (“1 week”) in portuguese, and “ago” in English, which just makes no sense. How can I edit the “ago”?
@breathelifein You may create a language file. See https://codex.ww.wp.xz.cn/I18n_for_WordPress_Developers#Translating_Plugins_and_Themes The pot file for the plugin is placed in the language directory in the plugin root directory.
