Spelling rule
The dge or ge rule
The answer
When /j/ ends a one-syllable word, it is spelled dge right after one short vowel (edge, bridge) and ge after a consonant, an r-controlled vowel or a long vowel (hinge, charge, cage). Our lexicon has 58 words in these groups and no exceptions.
When does the rule apply?
English words do not end in the letter j, so /j/ at the end needs another spelling, and the choice is between dge and ge. The e in both is silent; it keeps the g soft. The d in dge is the guard letter for a short vowel, exactly like the t in tch. Our tables split the ge words by what stands before the g: a consonant (hinge, lunge), an r-controlled vowel (charge, urge) or a long vowel (cage, huge). That split makes the reason visible.

Words that break the rule
None. No public word in our lexicon breaks this pattern.
How do you teach it?
Teach dge in the same week as tch, ideally the day after. Students who just learned "tch after one short vowel" will predict dge if you ask what the guard letter for /j/ would be. Then contrast "budge" with "bulge", "ridge" with "hinge" and "wedge" with "wage".
"Say 'smudge'. Is the vowel short? /u/, yes. Is it alone, right before /j/? Yes. So we write d-g-e. If we wrote 'smuge', the u and e would make it say /oo/. Now 'plunge'. Before /j/ there's /n/, a consonant. That's enough of a guard. Just g-e."
What is the common error, and the fix?
Students write "brige" for bridge, which reads with a long i, or "hindge" for hinge. The fix: underline the vowel and ask whether it is short and alone right before /j/. Yes means dge. A consonant or a long vowel before /j/ means ge.
Sort it: a hands-on activity
Build cards for every dge word in the table and a matching number of ge words. Students sort into dge and ge, then try reading each card with the other spelling ("brige", "hindge") to hear why the swap fails.
How this list was built
Every word comes from our lexicon of about 19,000 common words, each checked against a pronouncing dictionary and split into spelling units. Words a student meets in our assessments and progress-monitoring probes are left out, so practicing a list never rehearses a test. Rule groups are computed from each word's spelling units and its word sum (base plus suffix), then checked by hand; false word sums such as man + er for manner are removed.
"Readable after" is the first lesson in the lesson sequence at which our decodability engine finds every sound-spelling in the word taught; "not taught" means the word has a spelling the sequence does not cover, so it is read with help. You can check your own lists and passages with the free decodable text checker.
Questions people ask
Why does dge end with a silent e?
Without the e, the g would say /g/, as in rig. The e makes it soft, so it says /j/. The d adds no sound; it marks the short vowel.
What is the difference between ge and dge?
Both spell /j/ at the end of a word. Use dge right after one short vowel (edge, judge, bridge) and ge after anything else: a consonant, a vowel with r, or a long vowel.
Are there dge words with more than one syllable?
Yes. Knowledge, cartridge and porridge end in dge after a vowel in an unstressed syllable, and the rule still points the right way: a short vowel sits right before the /j/.
