Satem
By contrast, in the remainder of the Indo-European family (the then-called Centum languages), palato-velars lost their palatal component and merged with plain velars, while labio-velars remained distinct.
The Satem shift is conveniently illustrated with the word for '100', Proto-Indo-European *ḱmtom, which became e.g. Avestan satem (hence the name of the group), Lithuanian šimtas, Russian sto, etc., as contrasted with Latin centum (pron. [kentum]), English hund(red)- (with /h/ from earlier *k, see Grimm's law), Greek (he)katon, Welsh cant, etc.
