Examples
By CEFR Level

- Babies often produce labionasal sounds like 'mama' early on.
- The phonetician described the allophonic variation as a labionasal stop becoming a labiodental nasal before fricatives.
- The distinction between a labionasal and an oral bilabial plosive is crucial for diagnosing certain speech disorders.
Learning
Memory Aids
Mnemonic
Think of 'labio' (relating to lips, like 'labia') + 'nasal' (relating to the nose). A labionasal sound is made with your lips and your nose.

Common Pitfalls
Translation Traps (for Russian speakers)

- The English term is a direct calque of the Russian linguistic term 'губно-носовой'.
Common Mistakes
- Misspelling as 'labionazzle' or 'labionassal'.
- Confusing it with 'labiodental' (e.g., [f], [v]).
- Using it outside of a phonetic context.

FAQ
Frequently Asked Questions
Yes, the phoneme /m/ (as in 'man' or 'seem') is the most common example of a labionasal consonant in English. It is produced with both lips closed (bilabial) and the velum lowered, allowing air to escape through the nose (nasal).
'Nasal' is a broader category for any sound where air escapes through the nose (e.g., /m/, /n/, /ŋ/). 'Labionasal' is a specific sub-type, specifying that the active articulator is the lips. So, all labionasals are nasals, but not all nasals are labionasal (e.g., /n/ is an alveolar nasal).
It would be highly unusual and likely confusing. This term is a technical descriptor for linguists, speech therapists, or language students. In everyday talk, you would simply say 'm sound' or 'nasal m'.
Yes, the Russian phoneme /m/ (as in 'мама' [mama]) is a labionasal, just like its English counterpart.
