The linguist explains that the 'th' in 'thin' is a spirant.

Definition

1. Adjective:

   • Relating to a speech sound: Describes a consonant sound produced by forcing the breath stream through a narrow constriction in the vocal tract, creating audible friction. This is a technical term in phonetics.

2. Noun:

   • A type of consonant: A speech sound (consonant) characterized by a continuous flow of air through a narrow passage in the mouth, producing friction. It is synonymous with the term "fricative."

Usage Examples

• Adjective:

  • The sounds /f/ and /s/ are classic examples of spirant consonants.
  • In phonetic transcription, a spirant quality may be indicated with a specific diacritic.

• Noun:

  • The English phonemes /f/, /v/, /θ/ (as in thin), and /ð/ (as in then) are all spirants.
  • Linguists study how spirants differ from stops, like /p/ or /t/.

Advanced Usage

• Spirantization: This is a related phonological process where a non-fricative sound (like a stop /p/, /t/, /k/) changes or weakens into a spirant or fricative sound (like /f/, /θ/, /x/). This often occurs in historical sound change or between vowels.
  • Example: The historical change of Latin "focus" (hearth) to Spanish "fuego" (fire) involved the spirantization of the /k/ sound.

Variants and Related Words

• Fricative: This is the more common, fully synonymous term for "spirant" in modern linguistics.
• Sibilant: A subtype of spirant characterized by a high-pitched, hissing quality, such as /s/, /z/, /ʃ/ (as in ), and /ʒ/ (as in ).
• Approximant: A related but distinct category of consonant sounds produced with a wider constriction than a spirant, resulting in little to no audible friction (e.g., /w/, /j/ as in , /r/).

Synonyms

• Fricative (noun/adjective): The direct and most frequently used synonym.
• Friction consonant: A descriptive synonym.

Antonyms

• Stop (or Plosive): A consonant sound produced by completely blocking the airflow and then releasing it (e.g., /p/, /b/, /t/, /d/, /k/, /g/).
• Nasal: A consonant sound where airflow passes through the nose (e.g., /m/, /n/, /ŋ/ as in ).
• Approximant: As noted above, a sound with a more open articulation than a spirant.
