Here's why:
* Schwa sound: The schwa sound is a very short, unstressed vowel sound represented by the symbol /ə/ in phonetic transcription. It's often described as a "uh" sound.
* Apple: In "apple," the vowel sound is /æ/ as in "cat" or "hat." This is a distinct vowel sound, not the schwa sound.
Therefore, "apple" does not contain a schwa sound.
