consonantlike

Consonantlike refers to segments or phenomena in phonology that resemble consonants in certain respects but are not strictly classified as consonants within a language's phonological system. The term is informal and descriptive rather than a formal phoneme category. It is used to capture cases where articulation or distribution parallels consonants while the segment may lack a canonical consonant status in a given analysis.

In practice, researchers use the label to describe sounds that exhibit some consonant-like properties, such as a constricted vocal tract, a tendency to occur in syllable onsets or codas, or timing patterns typical of obstruents, even if the segment does not meet a strict set of criteria for the language's consonants. Syllabic consonants and some glides are common examples discussed as consonantlike in cross-language descriptions, because they synchronize with consonants in structure but may occupy a nucleus or behave differently from typical vowels.

The term is particularly useful in comparative work or descriptive phonology when a sound's status depends on the theoretical model. It signals that the segment shares more with consonants than with vowels in a given context, but without asserting a universal phonological category.
