Voiceless velar fricative to Voiceless velar plosive

Fortition (hardening) of the voiceless velar fricative [x] to the voiceless velar stop [k] is a documented shift. It frequently occurs as a result of language contact—when a language lacking the fricative phoneme adapts loanwords—or as part of a broader fortition process in specific phonetic environments.
