Proto-Indo-European

Reconstruction

The nominative singular form is underlyingly */ḱérd/, yielding the surface form *ḱḗr which is itself evident in Ancient Greek κῆρ (kêr) and Hittite 𒆠𒅕 (ker). This reconstruction is the only instance in PIE where a loss of */d/ after */r/ with compensatory lengthening of the preceding vowel occurred. It is not clear whether this is an isolated example, or a part of a broader process such as Szemerényi's law.
