The Greek alphabet

Greek also introduced three new consonant letters for its aspirated plosive sounds and consonant clusters: Φ (phi) for /pʰ/, Χ (chi) for /kʰ/ and Ψ (psi) for /ps/. In western Greek variants, Χ was instead used for /ks/ and Ψ for /kʰ/ The origin of these letters is a matter of some debate.
