Reduplication starting with a consonant
Normally the consonant is repeated, followed by an ε
χ, φ, θ (i.e. has an 'h' sound): The consonant is repeated without the 'h' sound, followed by an ε (κεχ, πεφ, τεθ). E.g. τεθερατευκα
σ, ζ, ξ (i.e. has an 's' sound): The normal rule applies (thus σεσ, ζεζ, ξεξ) but normally the initial consonant is then dropped leaving, effectively, just the addition of an ε. E.g ἐζητηκα, but also σεσωκα
