labiodental
C1Technical / Academic
Definition
Meaning
In phonetics, a sound made with the lower lip against the upper teeth.
In anatomy or phonetics, relating to or denoting this specific articulatory point of contact between the lip and teeth.
Linguistics
Semantic Notes
Primarily a term from phonetics and phonology. It describes a place of articulation, not a sound type (e.g., stops, fricatives). Therefore, sounds like /f/ and /v/ are *labiodental fricatives*.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. Terminology is identical in both linguistic traditions.
Connotations
None; purely technical.
Frequency
Equally low-frequency and specialized in both dialects, used only in relevant technical contexts.

Examples
By Part of Speech
adjective
British English
- The phonemes /f/ and /v/ are both classed as labiodental.
- A labiodental articulation is required for the correct pronunciation.
American English
- The patient's labiodental closure was incomplete.
- English has two common labiodental fricatives.
Examples
By CEFR Level
- The sounds 'f' and 'v' are made labiodentally, with your bottom lip and top teeth.
- Phoneticians categorize /f/ and /v/ as voiceless and voiced labiodental fricatives, respectively.
- The child's speech therapy focused on mastering the labiodental place of articulation.
Learning
Memory Aids
Mnemonic
Think of 'labio' (like 'lip' in 'labia') and 'dental' (relating to teeth). A 'labiodental' sound is made where your 'lip' meets your 'teeth'.
Conceptual Metaphor
PHONETIC ARTICULATION IS SPATIAL CONTACT (The sound is defined by the physical touch-point of two articulators).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Russian uses the calque "губно-зубной" (gubno-zubnoy), which maps directly and is accurate. No trap, but the word is highly specific.
Common Mistakes
- Mispronouncing it as /læbiodental/ instead of /ˌleɪ.bi.əʊˈden.təl/.
- Using it as a noun for the sound itself (e.g., 'He produced a labiodental') instead of as an adjective (e.g., 'a labiodental sound').

FAQ
Frequently Asked Questions
It is primarily an adjective (e.g., a labiodental sound). It can be used nominally (as a noun) in technical shorthand (e.g., 'labiodentals are common'), but this is less frequent.
Standard Russian does not have native labiodental fricatives like English /f/ and /v/. The Russian /f/ is borrowed and relatively rare. Russian /v/ is typically labiodental only in certain phonetic contexts; otherwise, it is more often a labiodental approximant or even bilabial.
Very rarely. Its primary and almost exclusive use is in phonetics and linguistics to describe speech sound articulation. In a broader anatomical sense, it could theoretically describe the region where lips and teeth meet, but this usage is highly unusual.
There is no single direct antonym. It is one of many places of articulation. Opposites would be sounds made at distant points in the vocal tract, such as 'glottal' (throat) or 'uvular' (back of mouth). A closer contrast is 'bilabial' (both lips).
