Here are a few examples:
* "co-op" - The "co" and "op" are distinct syllables, each with its own vowel sound.
* "di-et" - The "di" and "et" are distinct syllables, each with its own vowel sound.
* "re-al" - The "re" and "al" are distinct syllables, each with its own vowel sound.
In these cases, the vowels do not combine to form a single sound, but rather create two separate sounds, indicating separate syllables.
