Generally speaking language things are in the languages directory, not the templates directory. Suggest learning how to use the built in ZC tool of Developer's tool kit. Search for the text you want changed and find the file(s) in which it is defined. Then for the new language modify it there as well. I thought those particular things were part of the "core" language file. Have you installed a language pack yet for your desired language? If this continues to be an issue, may I suggest.
