Here's why:
* Schwa sound: The schwa sound is a very short, unstressed vowel sound often represented by the symbol /ə/. It's the most common vowel sound in English and is found in words like "about," "the," and "again."
* "Achieve" pronunciation: In "achieve," the vowel sound in the first syllable is a long "e" sound, similar to the vowel in "see" or "tree." This sound is not a schwa.
Therefore, "achieve" does not contain the schwa sound.
