In phonology, a syllable coda comprises the consonant sounds of a syllable that follow the nucleus, which is usually a vowel. The combination of a nucleus and a coda is called a rime. Some syllables consist only of a nucleus with no coda. Some languages' phonotactics, like that of Japanese, limit syllable codas to a small group of single consonants, whereas others allow any consonant phoneme or even clusters of consonants.
Here are some single-syllable words that have both a nucleus and a coda (the codas are specified in the International Phonetic Alphabet):
The following single-syllable words end in a nucleus and do not have a coda (phonologically):
