obstruent
C2Technical/Academic (Linguistics, Phonetics, Phonology)
Definition
Meaning
A phoneme (speech sound) produced by obstructing the airflow in the vocal tract, such as stops, fricatives, and affricates (e.g., /p/, /s/, /tʃ/).
In a broader linguistic sense, it refers to anything that obstructs or causes blockage. More rarely, it can be used adjectivally to mean 'causing obstruction.'
Linguistics
Semantic Notes
Primarily a technical term in phonetics/phonology. Its general adjectival use ('obstructing') is extremely rare and archaic outside of technical jargon. The noun form is standard.

Think: 'OBSTacle' in the vocal tract. An OBSTRUENT OBSTRUCTs the airflow.
Conceptual Metaphor
CONSONANTS ARE BLOCKAGES / SPEECH PRODUCTION IS A CHANNEL.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- The Russian phonetic term 'шумный согласный' (shumnyy soglasnyy) is a direct conceptual equivalent for 'obstruent.'
- Do not confuse with 'препятствующий' (prepyatstvuyushchiy), the general adjective for 'obstructing.' 'Obstruent' is a specific noun for a sound class.
Common Mistakes
- Mispronouncing it as /əbˈstruː.ənt/. Stress is on the first syllable.
- Using it in non-linguistic contexts, which sounds highly unnatural.
- Confusing it with 'abstract' or 'obstreperous'.

FAQ
Frequently Asked Questions
No, it is a specialised technical term used almost exclusively in linguistics, phonetics, and phonology.
Obstruents (stops, fricatives, affricates) involve a major obstruction of airflow, creating turbulence or a complete stop. Sonorants (nasals, liquids, glides, vowels) allow relatively free airflow and are typically voiced and more resonant.
Yes, but this is almost entirely limited to technical linguistic contexts (e.g., 'obstruent consonants'). Its general use meaning 'causing obstruction' is archaic and very rare.
No. Consonants are divided into obstruents and sonorants. Sonorant consonants include sounds like /m/, /n/, /l/, /r/, and /j/ (as in 'yes').
