The 20 Syllable Rules

Teachers should take a look at the importance of direct instruction in syllabication. The syllable rules provide helpful guides to proper pronunciation, spelling, and reading. Check out How to Teach Syllabication once you’ve skimmed the following syllable rules. The Twenty Advanced Syllable Rules are critical to accurate pronunciation, decoding, and spelling. Knowing the patterns of affixes and roots will also facilitate vocabulary acquisition.

Syllable Rule #1: Every syllable has a vowel. The common vowels are a, e, i, o, and u.

Syllable Rule #2: When the vowel is not at the end of a syllable, it has a short sound. The Vowel-Consonant (VC) and Consonant-Vowel-Consonant (CVC) patterns are called closed syllables. For example, bas-ket is a CVC-CVC word with the short vowels ă and ě.

Syllable Rule #3: When the vowel is at the end of a syllable, it has a long sound. The Consonant-Vowel (CV) and Consonant-Consonant-Vowel (CCV) patterns are called open syllables. For example, be-low is a VC-VC word with the long vowels ā and ō.

Syllable Rule #4: Vowel digraphs are paired vowels that have only one vowel sound. Usually the first vowel indicates the sound of the vowel digraph. For example, in the word boat, the vowel digraph is “oa” and the sound is /ō/. Usually keep vowel digraphs in the same syllable.

Syllable Rule #5: Base words are roots that form complete words. A root is the meaning-based syllable that may or may not connect to prefixes or suffixes. Usually keep the original spelling of the base word when connecting to prefixes and suffixes. For example, kick in kicking.

Syllable Rule #6: Compound words consist of two or three base words (roots that form complete words). Usually keep the original spellings of the base words in compound words. The spelling rules do not change the spelling of the base words. For example, bridesmaid.

Syllable Rule #7: An incomplete root is the meaning-based syllable that connects to prefixes and/or suffixes. Unlike a base word, the incomplete root is not a complete word. Both ending vowels and consonants can change when connecting to other roots and suffixes. Sometimes a vowel or consonant is either added or dropped. For example, vis in visible.

Syllable Rule #8: Keep the silent final “e” and the vowel before in the same syllable. The silent final “e” makes the vowel before a long sound if there is only one consonant in between the vowel and the “e”. For example, basement.

Syllable Rule #9: Vowel diphthongs are paired vowels that have two vowel sounds. For example, “au” in sauces. Like vowel digraphs, they stay in the same syllable.

Syllable Rule #10: Prefixes are meaningful word parts attached to the beginnings of words. More than one prefix can begin a word. For example, mis and under in misunderstand.

Syllable Rule #11: Suffixes are word parts attached to the endings of words. They can add meaning to the word or indicate a part of speech. More than one suffix can end a word. For example, on and al in seasonal.

Syllable Rule #12: Consonant digraphs, such as sh, and consonant blends, such as str, stay in the same syllable. For example, shallow and straighten. The /sh/ consonant digraph frequently changes to another consonant sound between different grammatical forms of the same root. For example, /sh/ to /k/ in musician and magic.

Syllable Rule #13: Keep the r-controlled vowels (ar, er, ir, or, and ur) in the same syllable. For example, er-ror.

Syllable Rule #14: Divide syllables between doubled consonants, for example for-gét-ting, unless the doubled consonant is part of a syllable included in a base word, for example ful-fill-ment.

Syllable Rule #15: Some short vowel sounds change to the soft /uh/ schwa sound with a different grammatical form of the same word. For example, in cónduct and conductor the “o” changes from a short vowel to a schwa.

Syllable Rule #16: Some long vowel sounds change to the soft /uh/ schwa sound with a different grammatical form of the same word. For example, in repeat and repetition the “e” changes from a long vowel to a schwa.

Syllable Rule #17: Some long vowel sounds change to the short vowel sound with a different grammatical form of the same word. For example, in nation and national the “a” changes from a long vowel to a short vowel.

Syllable Rule #18: Some silent consonants are pronounced when connected to different grammatical forms of the same root. For example, numb and number.

Syllable Rule #19: Many Greek and Latin prefixes change their spellings to match the roots to which they attach in order to make pronunciation easier. For example, in and mobile becomes immobile. These “chameleons” can change either their consonant or vowel spellings. Check out How to Teach Greek and Latin Prefixes, Suffixes, and Roots.

Syllable Rule #20: Many Greek and Latin suffixes are morphemes, which means that the word part is meaningful. For example, viewable. Other suffixes serve as inflections, which means that the suffix helps change the part of speech, but does not add meaning to the word. For example, started.

Syllable Transformers

Within the science of reading community, several in-house debates can get quite heated. One such topic is the value of teaching syllables or syllable types. Nora Chahbazi of EBLI comments,

I’m certain that teaching rules and syllable types is not necessary in order to learn to read well and quickly, but I am also acutely aware of the vitriol that can result from pushing up against these beloved and common instructional practices. When I even dip my toe into the ‘phonics rules and syllable types’ pool on social media or in discussions, and share about how phonics and multi-syllable words can be taught rules-free so student learning is more effective and efficient, the backlash is instant and severe.

Other respected voices in the science of reading community have different views on the subject of syllabication. According to Dr. Tim Shanahan (2021),

I would definitely teach syllabication. It clearly has value. Though the amount of such teaching can be pretty limited. Nevertheless, decoding instruction is not primarily or mainly about teaching students to sound out words. Such teaching, if successful, must instigate readers to perceive patterns and conditionalities within words (that’s what orthographic mapping and statistical learning are all about).

…So, yes, teach syllabication, but expose kids to the exceptions and teach them to use these divisions conditionally and flexibly.

Now, I’m not placing the two views as polar opposites. Some of these perceived differences may simply involve splitting fine hairs, such as whether to teach the terminology of syllable types or whether explicit or implicit instruction works better.

However, I’m steering somewhat clear of the controversy by dealing with a practical matter: After (or as) students acquire phonemic awareness and are knee-deep into decoding (phonics) and encoding (spelling), they also begin to recognize certain patterns in single-syllable words. Students don’t limit themselves to the phoneme (sound)-grapheme (spelling).  For example,

Precocious Paula notices that some sounds are used more than others: long and short vowels more than consonants. In fact, Paula observes that the teacher always writes the letters representing these sounds in different colors than the consonants.  She also sees that the charts on the walls have these same colors. Bonus-year Bobby notices that every word that his teacher writes has at least one of those vowel spellings. Already-reading Alma may even ask why one vowel sound can have more than one spelling. Conforming Carl may be upset that you won’t let him sound out each spelling in your list of Heart Words (high-frequency words which have a non-phonetic “part to learn by heart.” Analytic Amos may constantly point out those rimes (word families), despite your re-directs to the phoneme-grapheme correspondences.

You can’t (and shouldn’t) stop ’em, so teachers need to learn how to teach syllables.

In other words, through implicit or explicit instruction/practice, students will begin to develop recognition of syllable patterns. As more complex stories and advanced instruction layer in multi-syllabic words, most students identify these syllable patterns and apply this knowledge in their reading and writing.

Multi-syllabic decoding (phonics) and encoding (spelling) are the keys to the kingdoms of reading fluency and academic vocabulary. Reading multi-syllabic words is also a fundamental skill required for the new genres of reading that most students begin in 4th grade: their expository history and science texts.

Spelling Transformers Syllabication Strategy

Note: I am indebted to the late Dr. John Shefelbine of SIPPS and California State University, Sacramento (my MA alma mater) for introducing this basic strategy to me.

Time: The Spelling Transformers whole-class activity takes only a few minutes of concentrated instruction, a few times per week, over a five-week period.

I certainly agree with Dr. Shanahan that instructional time devoted to syllabication should be limited. Tim says,

In studies that found syllabication instruction to improve word recognition and reading comprehension, students received only 2-9 hours of teaching (yeah, even 2 hours of syllable training was beneficial).

Instructional Objectives: Students compare and contrast syllable patterns to read with automaticity by practicing syllable patterns in whole-class response.

Tactics: Rather than an inductive “Here are the rules-with examples-now apply them” approach, students practice many examples of each syllable pattern to achieve mastery of that pattern. The syllable patterns are both caught and taught, by using nonsense syllables in order to focus force students to analyze the phoneme-grapheme correspondences and not rely on previously orthographically mapped sight words. Note that I don’t find value in teaching the terminology (CVC, CVVC, etc.) of syllable types.

Materials/Preparation: The Spelling Transformers activity is designed to use the display projector. This instructional component is from my own comprehensive reading intervention program (promo below). Teachers and students love this fast-paced whole-class response activity.
