According to the Comparative Tables, the medial voiceless velar spirant [x] that developed from primitive [kʰ] vanished in Danian (PE19/23). In the Ossiriandic dialect, the same was true of primitive medial [kʰw], indicating that this change was after [w] vanished after medial velars in Ossiriandic. It may be that [x] first became [ɣ] as part of the general rule that medial voiceless spirants voiced after vowels before ultimately vanishing.

Medial [x] (“ch”) was preserved before a consonant in the name Gochressiel, so it is likely that [x] was only lost between vowels.
