Mixedgeminates

Mixedgeminates are a proposed phonological pattern in which certain consonants within a word are realized as geminate (long) consonants in some contexts while remaining singleton in others. The term signals a middle ground between full gemination and no gemination, capturing cases where lengthening is not uniformly applied across the word. Mixedgeminates are discussed mainly in theoretical phonology and experimental phonetics and are not claimed to be a universal feature of any particular language.

The phonological realization of mixedgeminates is context dependent. Gemination may be conditioned by factors such as stress, affix boundaries, syllable structure, or perceptual weighting of segments. As a result, the same consonant can show different durations in different morphemes or phonological environments. In some descriptions, mixedgemination co-occurs with changes in adjacent vowel length or timing, producing a set of complex cues that listeners must interpret. Acoustic measurements typically compare consonant duration, voice onset time, and spectral cues to distinguish mixedgeminates from simple geminates.

Typologically, mixedgeminates are considered relatively rare and are often discussed in the context of languages with rich morphophonology or in contact-induced variation and experimental data. They are of interest for exploring moraic structure, syllable weight, and how listeners parse variable length patterns during language processing or second-language acquisition.

Orthography and notation for mixedgeminates vary. In scripts that mark gemination by letter doubling, the exact point of lengthening may not always be consistently represented across contexts. Phonetic transcription uses standard gemination symbols, typically with a length marker [ː], to indicate extended duration where applicable.
