Results from acoustic analyses show that metaphony, expressed through raising or diphthongisation of mid stem vowels triggered by high suffix vowels, is present in nouns and adjectives, but significantly reduced or absent in verbs. In certain cases, verbs display paradigmatic levelling, with metaphonic patterns extending even to forms lacking a triggering environment. These findings suggest that grammatical category can influence sound change before full phonologisation. The reduced susceptibility of verbs to metaphony is attributed to their morpho-syntactic prominence and the functional need to preserve inflectional distinctions. Overall, the results highlight a complex interaction between phonetics, phonology, and morpho-syntax in the development of metaphony. The datasets were created as part of the project SoundAct which has received funding from the European Research Council (ERC) under the European Union’s Horizon Europe research and innovation programme (grant agreement No. 101053194). eng Greca Pia Harrington Jonathan 2026 400 410 450 470 10.5282/ubm/data.716 https://doi.org/10.5282/ubm/data.716 restricted Sound Change DCT analysis Metaphony Lausberg area Dialect variation V-to-V coarticulation Phonology-morphology interface en cc-by Greca Pia https://www.phonetik.uni-muenchen.de/Forschung/soundact/soundAct.html fak1314 Supplementary data: Is metaphony (and sound change) sensitive to grammatical category?
