Why don’t the Turuks (turkic) have a common language like the Arabs?

We could add the pure Turki words we have to this language. For example, in Turkish: teacher: "öğretmen," in Kazakh: umbrella: "kolshatır." We could also include words from works like the Orkhon inscriptions, Yenisei inscriptions, and Old Uyghur texts in the common Turkic language.
