Old South Arabian
There were several Old South Arabian languages (e.g. Awsānian), of which very little evidence has survived, however. A pair of possible surviving Sayhadic languages is attested in the Razihi language and Faifi language spoken in far north-west of Yemen. Although these varieties of speech have both Arabic and Sayhadic features. It is hard to classify them as either Arabic dialects with a Sayhadic substratum, or Sayhadic languages that have been restructured under pressure of Arabic.
