Sibilants and nonsibilants are categories of consonants used in phonetics and linguistics to describe the manner of articulation of certain sounds. The distinction primarily concerns the degree of hissing or fricative noise produced during their pronunciation.

Sibilant consonants are characterized by a sharp, hissing quality, typically produced when the tongue approaches or narrows the airway near the teeth, creating turbulent airflow. These sounds are often associated with the fricative consonants /s/, /z/, /ʃ/, /ʒ/, /t͡ʃ/, /d͡ʒ/, and their voiced or voiceless counterparts, depending on the language. The term "sibilant" derives from the Latin *sibilare*, meaning "to hiss," reflecting the distinctive sound produced. Sibilants are common in many languages, including English, Spanish, and French, and are often perceived as having a sharp or piercing quality.

In contrast, nonsibilant consonants lack this hissing characteristic. They generally produce a softer or more muted fricative sound, often articulated further back in the mouth or with less turbulence. Examples include the fricatives /f/, /v/, /θ/, /ð/, /h/, and the affricates /t͡s/, /d͡z/ (when not considered sibilant in certain contexts). These sounds are typically less harsh and may be articulated with the tongue closer to the roof of the mouth or lips.

The distinction between sibilants and nonsibilants is relevant in phonological analysis, as it can influence syllable structure, stress patterns, and even the perception of language sounds. Some languages treat sibilants as a phonemic category, creating contrasts that nonsibilants do not, which can affect meaning. For instance, in English, the difference between /s/ and /f/ is nonsibilant, while /s/ and /ʃ/ are both sibilants but distinct in articulation and perception. This categorization also plays a role in phonetic transcription, where symbols like [s] and [ʃ] are used to differentiate these sounds in written linguistic analysis.
