Voiceless velar fricative to Voiceless dental fricative

The shift from the voiceless velar fricative [x] to the voiceless dental fricative [θ] (represented here as 'th_vless') is documented as a form of dissimilatory shift and place movement, particularly in the historical development of Greek and through loanword adaptations.
