This category contains articles with Proto-Greek-language text. The primary purpose of these categories is to facilitate manual or automated checking of text in other languages.

This category should only be added with the {{ Lang}} family of templates, never explicitly.

For example {{ Lang| grk-x-proto|text in Proto-Greek language here}}, which wraps the text with <span lang="grk-x-proto">. Also available is {{ Lang-grk-x-proto|text in Proto-Greek language here}} which displays as Proto-Greek: *text in Proto-Greek language here.
