Proto-Sinaitic, end of the 19th century B.C. or beginning of the 18th.

The ancient Yemeni alphabet (also known as musnadالمُسند) branched from the Proto-Sinaitic alphabet in about the 9th century BC. It was used for writing the Yemeni Old South Arabiclanguages of the Sabaean, Qatabanian, Hadramautic, Minaean, Himyarite, and proto-Ge'ez (or proto-Ethiosemitic) in Dʿmt.

From Old English "snaca" which was derived from Proto-Germanic "snak-an-" which was derived from the Proto-Indo-European word (s)neg-o- (to crawl/creep)

Latin is derived from a language known as Proto-Italic, which gave rise to Latin and other extinct languages once spoken in Italy such as Oscan, Umbrian and Faliscan. Proto-Italic, in its turn, was one of the offspring of Proto-Indo-European, the ancestor of most of the modern-day European languages along with languages of western and southern Asia such as Kurdish, Farsi, Pashto and Hindi.

Proto-Italic and Proto-Indo-European were never recorded, but are known by historical inference from their attested daughter languages.

The verb is from the Anglo Saxon (old English) hætan,derived from the Proto-Germanic "khaitijanam."
