What are phonemes and syllables?

Phonemes and syllables in plain words

A phoneme is the smallest unit of sound in a spoken word, and you can take a word apart into those sounds. A syllable is a beat in the word, and each one is built around a single vowel sound.

Letters and sounds are not one to one. In ship the letters s and h work together to make a single sound, /sh/, so the word holds 3 phonemes, /sh/ /i/ /p/, and 4 letters. In box the letter x makes two sounds, /k/ and /s/, so the word holds 4 phonemes, /b/ /o/ /k/ /s/, and 3 letters.

A digraph is two letters that work together to make one sound: sh, ch and th. Each is a single phoneme, so it counts once and not twice. A silent letter adds no sound at all. The e in cake is silent and the a says its own name, /ā/, so cake has 4 letters and 3 phonemes: /k/ /ā/ /k/.

A syllable is a beat, and you can hear it without counting letters. Clap along: dog has one beat, apple has two, and butterfly has three. Each beat is one syllable, because each carries a vowel sound of its own.

Inside a syllable the sounds sit in two parts. The onset is the part before the vowel, and the rime is the vowel with what follows. In cat the onset is /k/ and the rime is -at.

ETS lists understanding that spoken words are made up of sounds, called phonemes, and syllables, among the topics for the Reading & Writing subtest (5758). Every example on this page is an English word, because ETS administers the test in English.

Why a paraeducator uses this in class

Phonemic awareness is knowing that a word is made of sounds, and that you can take those sounds apart and put them back together. It supports reading and spelling: a student who can hear each sound can match it to letters.

Blending and segmenting are the two moves. To blend, say the sounds one at a time and push them together into the word: /sh/ /i/ /p/ becomes ship. To segment, say the whole word and break it back into its sounds. Clapping the syllables is a third move, and it needs no reading: a student who cannot decode yet can still hear three beats in butterfly.

It also shows you where a student is taking a shortcut. If a student counts the letters in ship and calls the result four sounds, the count came from the spelling, not the speaking. Say the word out loud and raise one finger for each sound, and the count lands on three.

Worked example

A reader has to write the sounds in ship and say how many there are.

1. Write the letters. S, h, i and p: that is 4 letters.
2. Say the word slowly, one sound at a time: /sh/, then /i/, then /p/.
3. Count the sounds. There are 3 of them, so ship has 3 phonemes. The letters s and h make the single sound /sh/, which is how 4 letters give 3 phonemes.
4. Count the beats. Ship has one vowel sound, /i/, so it has 1 syllable. Clap once.
5. Name the parts. /sh/ is the onset of that syllable, and -ip is the rime.

Count one more the same way: cat is /k/ /a/ /t/, 3 phonemes and 3 letters, and cake is /k/ /ā/ /k/, 3 phonemes and 4 letters.
