A syllabic consonant is a consonant that forms a syllable on its own, or is the first consonant in a syllable with no vowels. The symbol of a syllabic consonant is a small vertical line below (as in n̩ ). This line is often omitted.
- Syllabic /m/: rhythm /ˈrɪðəm/ [ˈrɪðəm] or [ˈrɪðm̩].
- Most dictionaries, even those that use syllabic /n/ and syllabic /l/, don't use syllabic /m/. However some people can ommit the schwa in their pronunciation.
- Some people pronounce a syllabic /ŋ/, as in lock and key pronounced [ˌlɒk ŋ̍ ˈkiː]. In this case the small vertical line is written above the letter.
