The other Ancient Greek dialects, Ionic, Doric, Aeolic, and Arcadocypriot, likely had the same three-way distinction at one point, but Doric seems to have had a fricative in place of /tʰ/ in the Classical period, and the Ionic and Aeolic dialects sometimes lost aspiration (psilosis).
Out of the Ionic, Doric, and Aeolic dialects, which one had a consonant sound made by the friction of breath in a narrow opening, producing a turbulent air flow?
Doric
