to figure out if a word is a closed or open syllable word, look at the vowel (a, e, i, o, u)
wax
open syllables- word ends on a vowel
closed syllables- the vowel is followed by a consonant or more
therefore, wax is a closed syllable
(another example; fro-zen; fro would be the open syllable since it ends on O (vowel); while zen - the e (VOWEL) is followed by a consonant (n)
