consonantheavy

Consonantheavy is a descriptive term in phonology used to characterize languages or phonological systems in which consonants constitute a relatively large portion of the phoneme inventory and where syllables frequently include multiple consonants. It is not a formal typological category; rather, it serves as a heuristic for comparing phonological density between languages.

Consonant inventories described as consonant-heavy may be large or complex, featuring a wide range of stops, fricatives, affricates, nasals, liquids, and sometimes rare phonemes such as ejectives, implosives, or glottalized consonants. Some languages also permit rich onset and coda clusters, yielding syllable structures such as CC–V(C) or CCCVC. Vowel inventories can be modest or simple; the emphasis is on consonant density rather than vowel count. Phonotactic patterns in consonant-heavy languages often involve substantial consonant contact phenomena, including assimilation and cluster simplification rules.

The term is used across language families and regions, including some Caucasian, African, and Pacific languages, as well as others where the phoneme inventory emphasizes consonants. It interacts with orthography, morphophonology, and loanword adaptation, sometimes influencing how words are transliterated to preserve consonant distinctions or to simplify clusters.
