Hi Kobi Kai Calev,
Thank you for your input!
Tigrinya [tir] is already available on Amara as a subtitle language, as well as one of the languages you can add to your user profile. You can find it by typing in the language in the search field of the language list: the list does not always show in alphabetical order!
I hope this answers your request, but if there is anything else we can help you with, please do not hesitate to contact us again. We appreciate our users' help to make Amara better every day!
