= Proto-Human language
{wiki=Proto-Human_language}
Proto-Human language refers to a hypothetical, reconstructed, or ancestral language that is thought to be the common ancestor of all human languages. It is not a language that can be directly attested through historical documents or records, as it predates written history. Instead, linguists construct theories about Proto-Human language based on the similarities and commonalities observed across contemporary languages, including phonetics, vocabulary, grammar, and syntactic structures.
