THE VOWELS
A, E, I, O, U, and sometimes Y … and W? Yes, the letter W can behave as a vowel. It’s time to level up your Scrabble game, people. And, to all our grade-school peeps out there, get ready to knock the socks off your spelling teacher.
First, what is a vowel?
A, E, I, O, U, Y, and, as we’ll see, W, are called vowels, but let’s get technical. They are symbols (letters) that represent a special type of speech sound called a vowel.
According to phoneticians, a vowel is a speech sound that is made without significant constriction of the flow of air from the lungs.
In making vowels, the tongue can be at various heights in the mouth (e.g., high, mid, or low) and at various positions (front, central, or back). The lips can be variously rounded (cf. a long O and E). Vowels can vary in pitch and loudness, too.
If you do restrict or close your airflow in a significant way, you’re making a consonant. Where that restriction or closure occurs in your vocal tract determines what consonants you are making. B sounds are produced by bringing the lips together, for instance (bilabials). K sounds are produced by bringing the back of the tongue up to your soft palate (velars).
Why is W sometimes a vowel?
W is a rebel: it defies categories. To put it simply, it’s a little bit of both, vowel and consonant.
Linguists call it a semivowel or glide, “a speech sound having the characteristics of both a consonant and vowel, especially W in wore and Y in your and, in some analyses, R in road and L in load.”
Nope, this ain’t your spelling teacher’s alphabet, folks.
In English, W can behave this way at the beginning of a syllable, where it’s followed by a full-fledged vowel (e.g., wonderful). It can also behave this way as part of a diphthong (which is a vowel plus a glide), as in How now, brown cow?
Back in Old English, W was represented by an altogether different symbol: Ƿ/ƿ, called wynn. It was gradually replaced by the Norman (French) double U, which was literally two U‘s back to back, uu, hence its shape … and name, double-u!
