Voiceless uvular fricative to Voiceless uvular plosive

Fortition of voiceless uvular fricative [χ] to voiceless uvular stop [q], driven by increased oral constriction — typically in strong phonological positions such as gemination, word-onset, or post-pause. Because both sounds share the uvular place of articulation, the only change is in manner (fricative → stop). This is the reverse of the more commonly documented spirantization (q→χ) and occurs in environments where fortis or tense consonants are required. The most systematic documentation comes from Berber languages, where spirantization of historical stops produced [χ] in singleton position, but gemination regularly restores the stop quality to [q].

Language Examples

[χ] (singleton voiceless uvular fricative, from historical /q/ via spirantization)→[qː] (geminate voiceless uvular stop)— In Kabyle, historical Proto-Berber stops spirantized to fricatives in singleton position (/q/ → [χ]), but gemination blocks spirantization — 'gemination turns fricatives into stops.' The geminate of [χ] is therefore [qː], not [χː]. The rule 'spirantization never affects tense consonants' captures this positional contrast and is well-documented across northern Berber varieties.
[χ] (voiceless uvular fricative, coda reflex of /q/)→[q] (stop, in onset/word-initial position)— The underlying phoneme /q/ in South Bolivian Quechua spirantizes to [χ] in coda position, where the dorsal fricative is the standard reflex. In onset and post-nasal positions, the stop [q] is preserved or restored, illustrating positional fortition. Younger urban speakers show further weakening to [g]/[ɣ] (merger with Spanish /g/).
