Q: Is Y a vowel or a consonant?

Y can be both a vowel and a consonant. At the start of a word, making a 'yuh' sound, Y is a consonant, as in yes and yellow. In the middle or at the end of words like my, try, gym, and happy, Y stands for a vowel sound and is treated as a vowel.

In English, the main vowel letters are A, E, I, O, U. These letters stand for vowel sounds that are made with an open mouth and flowing air. The letter Y also acts as a vowel in many common words.

Vowel letters are different from consonant letters. In every English word, vowel letters help create the vowel sounds that form the center of each syllable. If a word has no vowel letters at all, it is usually not a normal English word.

Sometimes Y Is a Vowel

The letter Y is special. It can act as a consonant or as a vowel, depending on where it appears in a word.

Y as a Consonant

At the beginning of a word, when Y makes a “yuh” sound, it is a consonant, just like the letters B, C, or D.

yes, yell, yellow
yogurt, yarn

Y as a Vowel

In the middle or at the end of a word, Y often stands for a vowel sound such as /ī/ or /ē/. In these cases, Y is treated as a vowel letter.

my, try, cry
gym, symbol
happy, sunny, baby

That is why teachers often say: “A, E, I, O, U — and sometimes Y.” For more examples of how Y changes jobs, see Is Y a Vowel or a Consonant? once that page is ready.

Vowels support fluent reading. When children can quickly spot the vowels in a word, they can sound it out more confidently.
