What are Phonemes, Graphemes, and Digraphs?

What is a Phoneme, Grapheme, Digraph

We learn how to read by sounding out words phonetically and by matching sounds with letters or groups of letters.

Phonemes

Each sound that you hear in a word is a Phoneme. It’s the smallest unit of sound that makes up a complete word. This is not to be confused with the letter itself; Phonemes are only the sounds made.

Take the word “dog” for example. There are three Phonemes involved: the “d” sound, a short “aw” sound, and a “g” sound. The word “hope” is a three Phoneme word, too: the “h” sound, the long “oo” sound, and the “p” sound. And for something a little more difficult, the word “school” has four Phonemes: the “s” sound, a “k” sound, a long “uu” sound, and an “l” sound.

There are 44 Phonemes in the English language, consisting of 24 consonant sounds and 20 vowel sounds. Think of the different combinations of consonants and vowels (like “ch” or “ea”) that make unique sounds.

Graphemes

A Grapheme is a symbol used to identify a phoneme; it’s a letter or group of letters representing the sound. You use the letter names to identify Graphemes, like the “c” in car where the hard “c” sound is represented by the letter “c.”

A two-letter Grapheme is in “team” where the “ea” makes a long “ee” sound. A four-letter Grapheme can be found in the word “eight” where “eigh” makes a long “a” sound.

To confuse everyone, some Phonemes (sounds) can be spelled with different Graphemes (letters). The hard “c” sound can be spelled with a “c,” a “k,” or a “ck” Grapheme. Quite a few Graphemes can be used for the long “ee” Phoneme: “ee” as in Leeds, “ea” as in seam, “ie” as in brief, “ei” as in ceiling, and “e-e” as in theme.

Digraphs

Finally, a Digraph is a two-letter Grapheme that makes one sound. For example, consider the “ch” in choose, “sh” in shut, or “oa” in boat. A Split Digraph is when an “e” on the end of a word makes the middle vowel long, such as the the difference between “din” and “dine.” They both have three Phonemes (sounds), but the Split Digraph in “dine” makes the long “i” sound.

Now to test your understanding: what’s a Trigraph?

(Here’s a hint: The answer is not too “high” above your ability.)
