The less precise term Germanic, that appears in etymologies, dictionaries, etc., loosely refers to a language spoken in the 1st millennium AD,[citation needed] proposedly at that time developing into the group of Germanic languages—a stricter term for that same proposition, but with an alternative chronography, is Proto-Germanic language. As an identifiable neologism, Germanic parent language appears to have been first used by Frans Van Coetsem in 1994. It also makes appearances in the works of Elzbieta Adamczyk, Jonathan Slocum, and Winfred P. Lehmann.
