Help Your Child Say S: S Words for Speech Practice, by Position
Initial, medial and final s words with pictures, the z words that go with them, which words to start with, how to practice at home, and free picture cards.
S words for speech practice are sorted by where the s sound falls in the word: at the beginning (initial s, as in sun), at the end (final s, as in bus) or in the middle (medial s, as in pencil). A child working on s practices one position at a time, because a child can say s at the start of a word and still miss it at the end. Most children say s clearly by about 4 to 5, and z at about the same age.
The one rule for choosing where to start: begin where your child already says s best, which is usually the beginning of the word. Below are 36 s words and 24 z words, sorted by position, each with a picture card to print, plus how to practice them in 5 to 10 minutes a day.
What are initial, medial and final s words?
Initial, medial and final s words are words with the s sound at the beginning, in the middle or at the end. Speech-language pathologists sort practice words this way because a child can have s in one position and not yet in another. The Practice Portal of the American Speech-Language-Hearing Association (ASHA) describes practicing “sounds in various word positions (e.g., initial-word, within-word, and final-word positions)”.
The position is about the sound, not the letter. The s sound is spelled c in pencil, circle and juice, and the letter s often makes a z sound, as in nose and bees. That is why the z words on this page include rose and cheese.
Initial s words
Initial s words start with the s sound. These 12 are short, everyday words that can be pictured, each with one s and no s blend.
| Initial s words | |||
|---|---|---|---|
| sun | soap | sock | seal |
| saw | sub | six | seven |
| seed | sink | soup | circle |
Final s words
Final s words end with the s sound. A child who leaves the s off the end (“bu” for bus) is dropping a final sound, which has its own page on final consonant deletion.
| Final s words | |||
|---|---|---|---|
| bus | house | mouse | horse |
| juice | ice | dress | grass |
| goose | moss | octopus | walrus |
Medial s words
Medial s words have the s sound in the middle, between two other sounds. Some of them sit next to another consonant (basket, castle), which is still a medial s.
| Medial s words | |||
|---|---|---|---|
| pencil | dinosaur | bicycle | popsicle |
| basket | castle | glasses | dresser |
| whistle | astronaut | pacifier | bracelet |
Z words for speech: initial, medial and final z
Z is the same mouth shape as s with the voice switched on. Put a hand on the front of your throat and say “zzz” and then “sss”: z buzzes and s does not. Most children learn the two at about the same age, so z words are often practiced alongside s words. Fewer everyday words start with z than with s, so the initial list is short.
| Position | Z words |
|---|---|
| Initial z | zebra, zero, zoo, zipper, zucchini |
| Medial z | lizard, puzzle, wizard, easel, daisy, present, scissors |
| Final z | nose, rose, hose, cheese, bees, peas, keys, toes, eyes, shoes, fries, cookies |
For practice that sets s and z side by side, such as sip and zip or ice and eyes, use the s and z minimal pairs.
Which s words should my child start with?
Start with the position where your child already says s best, usually the beginning of the word, and with short words that have only one s. ASHA’s Practice Portal puts the principle plainly: “Instruction for a particular sound is initiated in the syllable context(s) where the sound can be produced correctly.” No credible source sets one fixed order for every child, so if the end of the word is easier for yours, start there.
Three more things make a first set easier:
- One s per word. Sauce and sister ask for two s sounds at once; save them for later.
- Words your child knows and can see. A picture card gives the word without you having to say it first every time.
- A few words, not the whole list. Six to twelve cards is a full session.
If your child sees a speech-language pathologist, use their list and their position first. The Norfolk and Waveney children’s speech and language therapy team (NHS) tells parents that “a therapist will tell you … whether to practise at the beginning, in middle or at the ends of words” (Norfolk and Waveney NHS).
How to practice s words at home
Practice in short daily sessions: you say the word, your child copies it, about 5 tries a card, for 5 to 10 minutes. The Norfolk and Waveney team puts the dose this way: “Practise little and often, 5-10 minutes every day is better than one hour once a week” (PDF). A survey of speech-language pathologists by Sugden and colleagues (2018) found home practice was most often prescribed five times a week for 10 minutes.
Pick one position
Choose the cards where your child already says s best, usually the beginning of the word. If your child sees a speech-language pathologist, use the position they are working on.
Say it, then your turn
Say the word clearly while you point at the picture, then let your child copy you. Stretch the s a little, sssun, so it is easy to hear.
About 5 tries a card
Go through the cards with about 5 tries each, then go through them again if it is still fun. Praise the try, not only the clear ones.
Stop at 10 minutes
Five to ten minutes most days does more than one long session a week. Stop while your child still wants to play.
Two cues help with the s itself. MyHealth Alberta’s speech sound activities, presented by a pediatric speech-language pathologist, describe s as the sound you make when you “spread your lips and make a smile” (MyHealth Alberta). Call it the snake sound and make it long: sssss. Praise the try rather than correcting every word, and say the word back clearly when it comes out wrong (“Yes, the sun!”) instead of asking for a repeat.
From s words to phrases and sentences
When your child says s clearly in single words most of the time, put the same words into short phrases, then sentences, then everyday talk. ASHA’s Practice Portal describes the usual steps as practice “at increasingly challenging levels (e.g., syllables, words, phrases/sentences, conversational speaking)”.
Keep the practice word where your child can see its picture:
- Phrases: my sock, a big bus, the hot soup, a red pencil, I see a zebra.
- Sentences: The sun is up. Look at the horse. I like ice in my juice. The lizard is in the grass.
- Everyday talk: pick one word for the day and use it at a meal, on a walk or at bath time.
Go back a step if the s starts to slip. It is normal for a sound to come out clearly in single words before it does in fast talk.
Games for practicing s words
Each game below asks your child to say the word to win, so the practice happens without drills.
- Snake hunt. Hide the picture cards around the room. Your child keeps a card by saying its word with a long snake sound.
- Feed the snake. Draw a snake on a box. Your child “feeds” it a card each time they say the word.
- Go fish or memory. Print two sets of cards. Asking “Do you have the sun?” or turning over a pair only counts when the word is said.
- Hop the s. Lay the cards in a path on the floor. Your child hops to the next card by saying the word on it.
- Sort by position. Mix initial, final and medial cards and sort them into three piles by where the s is. Saying the word out loud is what tells you the pile.
When the problem is s blends, a lisp or s and sh
This page practices a single s sound. Three related problems have their own pages.
- S blends (spoon, star, snake): a child who says “poon” for spoon is dropping one sound of a pair. The s blend word lists cover the blends for reading; the speech side is cluster reduction, one of the phonological processes.
- A lisp: a child whose s comes out with the tongue between the teeth (“thun” for sun) has a lisp. The words on this page are the right practice words for it, and the th minimal pairs practice the difference between “think” and “sink”.
- S and sh mix-ups (sip for ship): see s and sh minimal pairs.

When should I ask a speech-language pathologist?
Ask a speech-language pathologist if your child still cannot say a clear s by about 5, if people outside the family find their speech hard to understand, or whenever you are worried. A 2020 review of English consonant acquisition by Crowe and McLeod found s and z were acquired by 90% of children between 4;0 and 4;11, years and months. MyHealth Alberta gives “by 5 years of age” for s.
A 3-year-old whose s is not clear yet is usually on time, because s is still arriving at that age. For a quick at-home screening of the common speech patterns, use the picture check on the minimal pairs page. It is a screening, not a diagnosis, and it does not replace an evaluation. ASHA ProFind lists certified speech-language pathologists.
Frequently asked questions
What age should children start practicing medial 's' words?
There is no separate age for the middle of a word. Most children say s clearly by about 4 to 5, so practice usually starts when an s is still unclear around then, or when a speech-language pathologist suggests it. Many children practice the beginning and end of words first and add the middle once those come easily.
How often should S and Z words be practiced in therapy?
Little and often: 5 to 10 minutes most days does more than one long session a week, according to the NHS speech and language therapy team in Norfolk and Waveney. Speech-language pathologists commonly ask families to practice about five times a week for around 10 minutes.
How many final 's' words are generally suggested per practice sheet?
One page of 12 picture cards is plenty for a sitting. Aim for about 5 tries on each card, then go through the cards again if your child is still enjoying it. More tries help, so a short daily session with the same cards beats a long list done once.
Why do children struggle with medial 's' words and how can parents help?
In the middle of a word the s sits between two other sounds, with no pause before or after it, so the tongue has to reach the s and leave it again quickly. Practice the middle once the beginning and end are easier, say the word slowly with a slightly longer s (pen-sss-il), and let your child copy you.
When should a child start S sound speech therapy?
Ask a speech-language pathologist if your child still cannot say a clear s by about 5, if other people find their speech hard to understand, or if you are worried at any age. An evaluation tells you whether practice is needed and where to start.
Can z words help children differentiate voiced from unvoiced sounds?
Yes. S and z are made with the mouth in the same shape, and the only difference is that the voice is on for z. Put your child's hand on the front of their throat: z buzzes and s does not. Pairs such as sip and zip practice exactly that difference.
