|Era||mid-1st millennium BCE|
Taymanitic is the dialect and script of the oasis of Taymāʾ in northwestern Arabia, attested starting in the 6th century BCE, though references to the existence of an indigenous script in Taymāʾ are attested in outside sources from the 8th century BCE.
Taymanitic does not participate in the key innovations of Proto-Arabic, precluding it from being considered a member of the Arabic language family. Nevertheless, it shares one key isogloss with Northwest Semitic: the change w > y in word-initial position. Examples include yrḫ for *warḫum 'moon, month' and ydʿ for wadaʿa 'to know'.
