Në rikonstruksionin standard, njihen tre seri të dorsaleve: Labiovelars: * k, * g, * G Velars: * k, * g, * G Palatals: * k, * ǵ, * ǵh Në disa degë (për shembull greke, italike dhe gjermanike), palatet u bashkuan me velaret: PIE *keup- "dridhej (brendshëm)" u bë latinisht cupiō "dëshira" dhe *ḱm̥tom "qindra" u bë latin centum (shqiptuar ); por * kwo- "përemër interrogative" u bë quō "how? where?".
In the standard reconstruction, three series of dorsals are recognised: In some branches (for example Greek, Italic and Germanic), the palatals merged with the velars: PIE *keup- "tremble (inwardly)" became Latin cupiō "desire" and *ḱm̥tom "hundred" became Latin centum (pronounced ); but *kwo- "interrogative pronoun" became quō "how? where?".WikiMatrix WikiMatrix
