Some pairs of letters make one new sound.

Words to know

  • digraphTwo letters that make one sound together.

Learn It

Page 1 of 5

Look at ship

  • ship
  • shop

S and h sit side by side.

But you do not hear /s/ or /h/.

They make one new sound: sh.

Two more pairs

  • chip
  • thin
  • this

Ch makes one sound, like in chip.

Th makes one sound, like in thin.

Blend or digraph?

Try sh, ch and th. Then compare them with bl and st.
sh

You hear: /sh/

A digraph — one new sound instead

the soundship
sh — as in ship
Letterss and h — two letters
Sounds you hear1: /sh/
Can you hear s’s own sound?No
What is missingneither /s/ nor /h/
So it isA digraph — two letters, one sound

This is the one to notice. In sh you hear /sh/ — and that is neither /s/ nor /h/. The two letters gave up their own sounds and made a different one instead. So you cannot sound ship out letter by letter; you have to treat sh as a single thing that makes one sound.

Say the pair. Can you hear the first letter?

Yes? It is a blend. No? It is a digraph.

Count the sounds

  • fish

Fish has four letters.

But it has three sounds: f, i, sh.

One more: ck

  • duck
  • rock

C and k make one sound too.

It is the /k/ sound. Say duck.

What You Learned

  • Some pairs make one new sound.
  • Sh, ch and th are pairs like that.
  • Hear the first letter? It is a blend.
  • Ship has four letters and three sounds.
For the grown-up

A digraph is two letters making one sound that belongs to neither (sh, ch, th). A blend keeps both sounds (st, bl).

The test a child can run on any pair: say it, and listen for the first letter. Heard it, blend; not there, digraph. It works on pairs nobody taught them, where a memorized list does not. Th has two versions (thin, this); ck is a digraph whose one sound is the /k/ c already makes.
