S blends

S plus a consonant. The easiest blends to hear, because /s/ can be held and stretched for as long as a child needs.

Where Wiggler teaches it: Skill 4: Consonant Blends

Child explanation

Sssstop. You can hold the /s/ as long as you like, then say the next sound.

The rule

In an s blend both letters keep their usual sound. Because /s/ can be held, these are the easiest blends to segment.

What is really going on

S blends are usually introduced first among the clusters because /s/ is a continuant and can be prolonged, making the two-sound structure audible. They also occur word-finally (-st, -sk, -sp), which the other families mostly do not.

Position in the word

• Beginning of a word — The usual position. For example: stop, spin, swim, snap, skip.
• End of a word — As -st, -sk and -sp. For example: fast, last, desk, wasp.

Examples

Easy examples

stop, spin, swim, snap, skip

More examples

star, step, still, small, smell, snow, speak, spot, sport, scar, school, sweet, swing, fast, desk, must

Pseudo-words

Made-up words that follow the rule. A child who reads these has the pattern rather than the vocabulary.

stib, spam, snud, skep, swom

Contrast pairs

• top versus stop — One sound added to the front.
• nap versus snap
• pin versus spin

Teacher note

Start the blend work here. Holding the /s/ makes the structure obvious in a way that /b/ in black never can, and children who succeed on s blends approach the others expecting to succeed. Note that three-letter blends — scr, spl, spr, str — are all s blends with one more sound.

Learn these first

• The consonants that keep one sound — b d f h j k l m n p r t v w z — Fifteen consonants represent the same sound almost everywhere they appear. They are the reliable floor the rest of the system is built on.
• The five short vowels — a e i o u in a closed syllable — A single vowel with a consonant after it and nothing else is usually short. This is the rule that makes CVC words decodable.

Related rules

• Three-letter blends — scr spl spr str squ shr thr — Three consonants in a row. Every one begins with s, sh or th, and the rest is a blend the child already knows.
• L blends — bl cl fl gl pl sl — Two consonants, two sounds, said quickly. Nothing new to learn — the letters keep the values the child already knows.
• R blends — br cr dr fr gr pr tr — The largest blend family. Dr and tr are the two children most often hear as a single sound, because they genuinely shift in speech.
• Final blends — -st -nd -mp -nt -ft -lt -sk -lp — Blends at the end of a word. Harder to hear than initial blends, because the final consonant is quieter in ordinary speech.

• Previous in Consonant blends: R blends — br cr dr fr gr pr tr — The largest blend family. Dr and tr are the two children most often hear as a single sound, because they genuinely shift in speech.
• Next in Consonant blends: Three-letter blends — scr spl spr str squ shr thr — Three consonants in a row. Every one begins with s, sh or th, and the rest is a blend the child already knows.
