Which of the following best describes a closed vowel?

A closed vowel is best described as a vowel sound that is contained within a closed syllable. In linguistics, a closed syllable is one that ends with a consonant. This affects the pronunciation of the vowel within that syllable, often producing a sound that is more distinct and clear than in open syllables, where the vowel sound may linger longer because it is followed by no consonant.

In a closed syllable, the vowel is typically short, as in words like "cat" or "dog," where the vowel sound is surrounded by consonants. This characteristic of closed syllables helps define the closed vowel sound in a straightforward manner, focusing on the sound's position in relation to adjacent consonants.
