The AR pattern usually makes the /ar/ sound, like in car and star.
Examples: car, star, farm, park, cart, dark, shark
R-controlled vowels are one of the trickiest vowel patterns for early readers. On this page you will learn what bossy R vowels are, how to pronounce AR, ER, IR, OR and UR, see word lists for each pattern, and get simple teaching ideas and printable practice suggestions.
This page covers one specific vowel topic in a clear way and links to the next lessons readers usually need.
R-controlled vowels (also called bossy R vowels) are vowels that are followed by the letter R and do not make their usual short or long sound. Instead, the R changes or ??ontrols??the vowel sound. The main patterns are AR as in car, ER as in her, IR as in bird, OR as in corn, and UR as in turn. In many accents, ER, IR and UR all make the same /er/ sound.
R-controlled vowels are usually taught after children can read and spell short vowel CVC words and have been introduced to basic long vowel patterns like Magic E words and common vowel teams. They are often called ??he third step??in vowel instruction: short vowels ??long vowels ??r-controlled vowels.
When a vowel is immediately followed by the letter R in the same syllable, the R changes the vowel to a new r-controlled sound and the vowel is no longer clearly short or long.
Before starting r-controlled vowels, it helps to quickly review short vowel words and long vowel words so students can clearly hear how the R changes the sound.

All r-controlled vowel words fall into one of five spelling patterns. The sound of AR is different from ER, IR, UR and OR. Many teachers start with AR, then teach ER, IR and UR together, and save OR for last.
The AR pattern usually makes the /ar/ sound, like in car and star.
Examples: car, star, farm, park, cart, dark, shark
ER is the most common spelling for the /er/ sound in English words.
Examples: her, fern, term, herd, clerk, tiger
IR often makes the same /er/ sound as ER and UR in many accents.
Examples: bird, girl, first, third, shirt, dirt
OR usually makes the /or/ sound, like in fork and storm.
Examples: or, corn, fork, horn, storm, short
Like ER and IR, UR often makes the /er/ sound in many English words.
Examples: urn, fur, turn, curl, hurt, nurse
Use these word lists as a reference for planning lessons, sorting words into word families, or creating your own worksheets and games.
| Pattern | Sound | Common words |
|---|---|---|
| ar AR | /ar/ as in car | car, star, far, farm, yard, card, park, dark, bark, hard, harp, shark |
| er ER | /er/ as in her | her, fern, term, herd, verb, clerk, serve, tiger, letter, better, winter |
| ir IR | /er/ as in bird | bird, girl, sir, first, third, shirt, skirt, dirt, firm, swirl, birthday |
| or OR | /or/ as in corn | or, for, corn, horn, fork, sort, short, storm, torch, north, morning |
| ur UR | /er/ as in turn | urn, fur, turn, curl, hurt, burn, burst, surf, nurse, church, turtle |

R-controlled vowels are easiest to understand when they are compared directly to short vowel and long vowel words that students already know. The examples below show how adding R changes the vowel sound.
| Short vowel word | Long vowel word | R-controlled word | Sound change |
|---|---|---|---|
| cat (short A) | cake (long A) | cart (AR) | /?/ ??/?/ ??/ar/ |
| bed (short E) | these (long E) | bird (IR) | /?/ ??/?/ ??/er/ |
| sit (short I) | kite (long I) | shirt (IR) | /?/ ??/?/ ??/er/ |
| hop (short O) | hope (long O) | horn (OR) | /?/ ??/?/ ??/or/ |
| cup (short U) | cube (long U) | turn (UR) | /?/ ??/?/ ??/er/ |
The key to teaching r-controlled vowels is to keep the pattern simple, use lots of word sorting and reading practice, and always connect new words back to short and long vowels students already know.
Step 1: Teach AR by itself (car, star, farm). Step 2: Teach ER, IR, UR together as /er/ spellings. Step 3: Teach OR and contrast /or/ with short O and long O. Step 4: Mix all five patterns in reading and spelling practice.

R-controlled vowels are vowel + R combinations where the letter R changes the usual vowel sound. Instead of a clear short or long vowel, the sound becomes a new r-controlled vowel sound such as /ar/, /er/ or /or/. The main patterns are AR, ER, IR, OR and UR.
They are called bossy R vowels because the R ??osses??the vowel and changes its sound. Teachers often say, ??hen R comes after a vowel, it is so bossy that the vowel cannot say its short or long sound any more.??
In many accents of English, ER, IR and UR all make the same /er/ sound, as in her, bird and turn. Because of this, they are often taught together as ??hree ways to spell the /er/ sound.??
R-controlled vowels are usually taught after short vowels and basic long vowel patterns like silent E and common vowel teams. Many programmes place r-controlled vowels in late Grade 1 or early Grade 2, once students can already decode simple words with confidence.
Many students find ER, IR and UR the most confusing because they often sound the same. It helps to teach them together, use colour coding for each spelling, and give plenty of reading and spelling practice with all three patterns mixed together.
