Recorded sources

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that natural languages exist in which s and sh sounds are distinct phonemes?

Yes. Multiple phonetic and phonological studies document natural languages that maintain a phonemic distinction between s and sh sounds.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked

The analysis

The claim that natural languages exist with distinct s and sh phonemes is a standard linguistic fact supported by numerous phonetic and phonological studies in the literature (e.g., English, Japanese, Slavic languages, and sibilant harmony systems). Papers [3], [5], [7], and [9] all explicitly reference or rely on the phonemic distinctness of [s] and [ʃ] ('sh') in natural languages. There is no evidence in the provided sources refuting this well-established linguistic universal.
