There is a certain relationship to the T, as both sounds are very similar
The Greeks adopted the letter as a delta . The approach of the triangle has been omitted. In the pre-classical period, the triangle was sometimes also shown rounded, depending on the particular writing tool. The Etruscans adopted the rounded shape of the delta. Since the Etruscan language did not have voiced consonants like [d], the letter was rarely used, although it was retained. The Romans took over the letter from the Etruscans, closed it off with the base line and used it again to represent the [d] sound present in Latin .
