Alveolar trill to Glottal stop
The alveolar trill /r/ can undergo debuccalization or reduction, leading to its replacement by a glottal stop /ʔ/ in certain phonetic environments. This transformation often involves a loss of oral articulation and a shift to a glottal articulation, sometimes as a result of lenition or as a strategy for hiatus resolution.
