PIE cannot be more centum-like or more satem-like. Both groups lose a
distinction that we think existed in PIE, ending up with a two-way contrast
where PIE had three. Both groups show phonological development of the
sound *k' (and *g' and *g'h), one group shifting it to various sibilants,
the other to a velar plosive.
