Understanding R-Controlled Syllables + VIDEO

By the time students begin learning R-controlled syllables, they’ve usually already worked with Bossy R vowel patterns like:

• ar
• or
• er
• ir
• ur

They’ve practiced hearing the sounds, reading the patterns, and spelling words with those vowel combinations. The next step is learning how those same patterns work inside syllables and larger words.

That’s where students begin connecting R-controlled vowels to syllable division.

In structured literacy and Orton-Gillingham, R-controlled syllables are the “R” in REVLOC. REVLOC helps students identify syllable types in a consistent order while decoding larger words.

One thing that can confuse students at first is that some R-controlled syllables look closed.

For example: fir

At first glance, it may look like a closed syllable because the vowel is surrounded by consonants. But because the vowel is followed by an R, the syllable is actually R-controlled.

That distinction matters when students begin dividing and reading larger words.

In this video, we walk through:

• how R-controlled syllables work
• why they “trump” other syllable types in REVLOC
• how these patterns connect to Hornet words
• and how syllable division helps students read larger words more efficiently.

A Quick Example

Take the word: thunder

When students divide the word:
thun / der

the word becomes more manageable because students can recognize the familiar R-controlled chunks inside the larger word.

That’s one reason syllable division is so important. Students stop trying to sound out the entire word at once and begin recognizing readable parts.
