The voiceless dental stop survived initially from Primitive Elvish into Ilkorin (PE19/18), but it became [d] after vowels (PE19/23) and became [θ] (“th”) after liquids and voiceless stops. It was preserved medially in some clusters, notably [st] and sometimes (final) [nt], though primitive medial [nt] became [nd].
