friktywne

Friktywne, in English fricatives, are a class of consonant sounds produced with a narrow constriction in the vocal tract that causes turbulent airflow. This turbulence generates audible friction rather than a complete blockage of the airstream, which distinguishes fricatives from stops and from more open consonants.

Fricatives are typically described by two main features: voicing and place of articulation. They can be voiceless (no vocal fold vibration) or voiced (with vibration). They are articulated at several places in the vocal tract, including labiodental (for example f, v), dental and alveolar (such as θ, ð, s, z), postalveolar and palatal (ʃ, ʒ, ɕ, ʑ), velar (x), and glottal (h). Some fricatives are sibilants, producing a hiss-like sound with higher turbulence (e.g., s, z, ʃ, ʒ), while others are non-sibilants with a softer friction.

Friktywne are common across languages and form important contrasts in phonemic inventories. Languages may differ in which fricatives they have, how they are distributed by position within syllables, and how they interact with vowels and neighboring consonants. In phonology, fricatives can undergo allophonic variation, devoicing in certain contexts, or become sources for sound changes such as the development of affricates or changes in place of articulation.

In Polish linguistic terminology, friktywne denotes the broader category of fricatives used to describe these sounds in Polish and other languages. They are an essential element of the consonant system and contribute significantly to phonotactic patterns and intelligibility.
