Here's why:
* Syllable: A syllable is a unit of pronunciation consisting of a single vowel sound, with or without surrounding consonants.
* First Syllable: The first syllable is simply the first unit of pronunciation in a word.
So, to rephrase your question, you might be asking:
* "What are words that have more than one syllable?"
* "What are words that have a stressed first syllable?"
