ST Blend: Speech Therapy Guide, Words & Games
The /st/ blend is written /st/ in the phonetic alphabet, and most children master it by age 5. This guide covers how to make the /st/ blend, 42 practice words split across initial, medial, and final position, and the errors children make most often.
Example ST Blend words: still, stop, stay, start (beginning); understand, sister, mistake, yesterday (middle); just, first, last, must (end).
The /st/ blend joins the /s/ and /t/ sounds — the "st" in star, stop, stand and story. It is also one of the most common ways English ends a word (fast, best, most), so it is worth practising at both ends of the word.
How to Make the ST Blend
Hold "ssss" and then tap the tongue tip up for the /t/ without letting the air stop: "ssss-tar". Final /st/ is a different job — there the risk is the word trailing off into "fas". Ask your child to finish the word with a crisp /t/ they can hear.
IPA Symbol: /st/
Most children master the /st/ blend by age 5. Blends arrive after the sounds they are made of: the /S/ and /T/ sounds each have to be reliable on their own before the cluster will hold, which is also the order to practise them in. Two-sound blends are generally in place somewhere between ages 4 and 7, tracking the sounds inside them — the ones containing /L/ or /R/ come in later than the rest.
Common ST Blend Errors
- Cluster reduction — producing only the /T/ sound and dropping the rest of the blend. This is by far the most common blend error.
- Cluster reduction — producing only the /S/ sound and dropping the rest of the blend. This is by far the most common blend error.
