Aspirated consonant
Some forms of Greek before the Koine Greek period are reconstructed as having aspirated stops. The Classical Attic dialect of Ancient Greek had a three-way distinction in stops like Eastern Armenian: /t th d/. These stops were called psila, dasea, mesa "thin, thick, middle" by Koine Greek grammarians.
