What type of syllable is represented by the words "lilac" and "tulip"?

The correct choice highlights that "lilac" and "tulip" contain open syllables. An open syllable is characterized by a syllable that ends in a vowel sound, meaning the vowel is not followed by a consonant. In the case of "lilac," the first syllable "li" is open because it ends with the vowel 'i'. Similarly, in "tulip," the first syllable "tu" is also open as it ends with the vowel 'u'. Both examples demonstrate that these syllables create a vowel sound as the last phoneme, which is the definitive feature of an open syllable.

This understanding is crucial as it contributes to phonological awareness and can impact reading and spelling strategies for students.
