The aim of this article is to characterize some lingual traits of the dialect spoken by ʽĪšɛ with regards to some selected socio-cultural aspects. ʽĪšɛ is a woman of more than one hundred years old, living in one of the villages of Testour district in North West Tunisia, accidently discovered by a Tunisian TV program in 2018. The examination being conducted here shows before all how ʽĪšɛ’s idiolect is strongly rooted in her geo-cultural environment, lingually and socially. Both similarities and differences between ʽĪšɛ’s idiolect and the General Tunisian as well as some other Tunisian dialects are also observed. What is more, ʽĪšɛ’s idiolect, living and intelligible beyond the boundaries of Tunisia up to present days, has stood thus the communicative test of time.
