ENGLISH PHONOLOGY

Phonology is defined as the study of sound patterns and their meanings, both within and across languages.

An example of phonology is the study of different sounds and the way they come together to form speech and words - such as the comparison of the sounds of the two "p" sounds in "pop-up."

A vowel is a particular kind of speech sound made by changing the shape of the upper vocal tract, or the area in the mouth above the tongue. ... These letters are vowels in English: A, E, I, O, U, and sometimes Y. It is said that Y is "sometimes" a vowel, because the letter Y represents both vowel and consonant sounds.

A consonant is a speech sound that is not a vowel. It also refers to letters of the alphabet that represent those sounds: Z, B, T, G, and H are all consonants. Consonants are all the non-vowel sounds, or their corresponding letters: A, E, I, O, U and sometimes Y are not consonants.

the example In hat, H and T are consonants.
