Which of the following describes a closed syllable?

A closed syllable is defined as a syllable that ends in a consonant, which typically results in a short vowel sound. In the word "napkin," the first syllable "nap" ends with the consonant "p," and this causes the vowel sound to be short. The structure of a closed syllable is typically a consonant-vowel-consonant pattern, which is exemplified here.

In contrast, the other options either contain open syllables or do not meet the criteria for a closed syllable. For instance, "lilac" has the first syllable "li" ending in a vowel, making it an open syllable. The word "shake" has a single syllable that ends in a vowel sound, making it open as well. Lastly, "bread" does contain a closed syllable, but it is a single syllable word where the closing consonant is part of the entire word, rather than exemplifying the structure that the question focuses on. Hence, "napkin" most effectively represents a closed syllable.
