S. initial [s] vanished before spirants; [s{ɸθx}-] > [{ɸθx}-]

Any initial s before spirants was lost as part of the general process whereby initial s + voiceless stops became initial voiceless spirants. For further details, see the discussion of the first stage of this sound change: voiceless stops became spirants after initial [s]. Based on Noldorin evidence, it seems the second stage of this sound change occurred after the Old Noldorin/Old Sindarin period:

As the last example shows, this change must have occurred before initial [x-] became [h-]: skh- > kh- (or ch-) > h-.

Conceptual Development: See the discussion in the entry on how voiceless stops became spirants after initial [s].
