A digraph is two letters representing one speech sound. A consonant blend is a group of neighboring consonants whose separate sounds can still be heard. In ship, sh represents one sound. In stop, s and t represent two sounds: /s/ and /t/.
That small difference changes how you help a child read or spell the word. You keep sh together when identifying sounds in ship. You listen for both sounds in st when working with stop. The University of Florida Literacy Institute’s phoneme–grapheme guidance explains this distinction.
The slashes in this guide mark sounds, not letter names. /s/ means the sound at the beginning of sun, rather than “ess.” These are parent-friendly sound spellings, not a full phonetic alphabet.
The difference at a glance
- Digraph: two letters, one sound. Examples include sh in ship and ch in chin.
- Consonant blend: adjacent consonants with separate sounds. Examples include st in stop and fl in flag.
- Blending: the action of joining sounds to say a word. Children use blending to read words with digraphs, consonant blends, and ordinary single-letter spellings.
A child blends /sh/ /i/ /p/ to read ship, even though sh is a digraph. If the terminology feels crowded, our explanation of blending and segmenting shows how joining sounds for reading relates to separating sounds for spelling.
Why ship has three sounds and stop has four
A phoneme is an individual speech sound. A grapheme is the letter or letter group that represents a sound in a word.
Look at ship:
- Letters: s, h, i, p. There are four letters.
- Sounds: /sh/ /i/ /p/. There are three sounds.
- Sound spellings: sh, i, p. There are three graphemes.
Now look at stop:
- Letters: s, t, o, p. There are four letters.
- Sounds: /s/ /t/ /o/ /p/. There are four sounds.
- Sound spellings: s, t, o, p. Each sound has its own single-letter grapheme here.
Both words have four letters, so letter counting alone cannot tell you the number of sounds. The Western Australian Department of Education’s phonemic awareness and phonics resource uses ship to illustrate this difference.
Say the vowels as they sound in the example words, using your familiar accent.
Digraph and blend examples
Start with a small set whose spellings your child has learned.
Words with consonant digraphs
- ship: /sh/ /i/ /p/. The initial sh represents one sound.
- fish: /f/ /i/ /sh/. The final sh represents one sound.
- chin: /ch/ /i/ /n/. The initial ch represents one sound.
- thin: /th/ /i/ /n/. The initial th represents one sound.
Each of these words has four letters and three phonemes. Digraphs can occur at different places in words. A spelling can also represent different sounds in different words: th in thin sounds different from th in this, but it represents one phoneme in each. Reading Universe’s consonant digraph overview provides more examples.
Words with consonant blends
- stop: /s/ /t/ /o/ /p/. Listen for both sounds in st.
- flag: /f/ /l/ /a/ /g/. Listen for both sounds in fl.
- tent: /t/ /e/ /n/ /t/. Listen for both sounds in the final nt.
- lamp: /l/ /a/ /m/ /p/. Listen for both sounds in the final mp.
Each of these examples has four letters and four phonemes. Blends are also called consonant clusters or adjacent consonants. The Department for Education’s reading framework emphasizes attending to the individual phonemes in these clusters before joining them to read a word.
Try a short sound-counting activity
You need paper and a pencil. Use ship and stop only if your child has been taught their spellings, including sh. Otherwise, choose familiar words from the same pattern your child is learning at school.
- Say ship together. Model its sounds: /sh/ /i/ /p/. Make one finger tap for each sound.
- Draw three spaces. Write sh in the first space, i in the second, and p in the third. Point out that two letters share the first sound space.
- Read it back. Point to each sound spelling, join the sounds, and say ship naturally.
- Try stop. Say /s/ /t/ /o/ /p/ and make four taps. Draw four spaces, then put one letter in each.
- Notice what changed. Say, “Both words have four letters. In ship, s and h work together for one sound. In stop, we hear /s/ and /t/.”
You can do the writing while your child points or taps. If they want another example, try fish or lamp after checking the spellings are familiar. A couple of words can be enough for this practice idea; it is not a test or a complete teaching program.
Connecting spoken sounds with their written spellings follows the broad guidance in the U.S. Institute of Education Sciences’ foundational reading practice guide.
What if a sound gets split or missed?
Your child says /s/ /h/ at the start of ship. Point to sh together and give the sound. Try, “These two letters spell /sh/ here. Let’s use that sound to read the word.” Then model the whole word and read it together.
Your child reads stop as top. Return to the beginning and help them notice s before t. Say the full sequence together, then join it into the word. Keep /t/ short rather than adding an “uh” sound.
Your child notices every sound but cannot join them. Keep the spelling pattern familiar and give more help with the joining step. Our step-by-step blending guide models this process. For a difficulty that keeps recurring, use the guide for children who know sounds but cannot yet blend and ask their teacher which prompts to use at home.
Common questions
Is sh a blend or a digraph?
In ship and fish, sh is a digraph: two letters represent one sound. You still use the skill of blending to join that sound with the rest of the word.
Can a word contain both a digraph and a blend?
Yes. In splash, spl contains three consonant sounds, while sh represents one sound. The word has six letters and five phonemes: /s/ /p/ /l/ /a/ /sh/. Save it for practice after those spellings and longer sound sequences have been introduced.
Do digraphs always contain consonants?
No. Sh is a consonant digraph, while ee in feet is a vowel digraph. This guide focuses on consonant digraphs because they are easily confused with consonant blends.
Should we learn digraphs or blends first?
Follow the sequence used by your child’s school or phonics program. For home practice, choose words containing spellings already taught. If those words are still too demanding, return to familiar three-letter CVC words and ask the teacher what to add next. There is no need to turn this distinction into an age deadline.
Keep the focus on the sounds
The useful question is: “What sounds do these letters represent in this word?” Start with a familiar example, show how the sounds match the spelling, and read it together.
