How can I translate an affiliate into different languages

The extension uses the same logic for translations as default Magento. More details:

Our i18n files should be located at: vendor/mirasvit/module-affiliate/src/Affiliate/i18n/

Create a separate file for your language (en_US.csv, de_DE.csv). The names for all languages can be found via this command:

php -f bin/magento info:language:list

Override the strings in your dictionary file:

"Original line" , "Translated line"

Run this command to see the changes:

php -f bin/magento setup:static-content:deploy

php -f bin/magento cache:flush

The custom themes will be displayed instead of the default for your language.
