Pronunciation: Soft Letters, Silent Letters, and Syllable Stress

You can label every piece of a word and still stumble the first time you say it out loud. Cyst, cardiac, pneumonia, and psychiatry share the same alphabet and the same rules from Lessons 1 and 2, but the sound each one makes comes down to a handful of pronunciation patterns most textbooks skip past. Soft and hard letters, silent letters at the front of a word, and where the stress falls decide how a term actually sounds, and ten minutes of practice with all three will keep you from mispronouncing most of what's coming in this course.

Soft C and Hard C

The letter c makes two different sounds, and which one you get depends entirely on the letter right after it.

• C before e, i, or y is soft, and sounds like an s. Cyst sounds like "sist." Cervic/o sounds like "SER-vih-koh." Cyanosis sounds like "sy-uh-NOH-sis."
• C before a, o, or u is hard, and sounds like a k. Cardi/o sounds like "KAR-dee-oh." Colon sounds like "KOH-lun." Cutaneous sounds like "kyoo-TAY-nee-us."

Say cyst and cardiac side by side and you can hear the switch happen on the same letter.

Soft G and Hard G

The letter g follows the same pattern as c, with the same three vowels flipping the sound.

• G before e, i, or y is soft, and sounds like a j. Gingiva sounds like "jin-JY-vuh." Geriatric sounds like "jer-ee-AT-rik." Arthralgia sounds like "ar-THRAL-juh."
• G before a, o, or u is hard, and sounds like the g in "go." Gastr/o sounds like "GAS-troh." Gonad sounds like "GOH-nad."

Watch for -algia and -gia endings. Both end in a soft g, since the g is followed by i, and that's an easy one to say wrong the first time you see it in print rather than hear it said.

Silent Letters at the Start of a Word

A handful of Greek-derived combinations drop the first letter entirely when they open a word.

• Pn- drops the p. Pneumonia sounds like "noo-MOHN-yuh." Pneumothorax sounds like "noo-moh-THOR-aks."
• Ps- drops the p. Psychiatry sounds like "sy-KY-uh-tree." Psychosis sounds like "sy-KOH-sis."
• Pt- drops the p. Ptosis sounds like "TOH-sis." Pterygium sounds like "tuh-RIJ-ee-um."

The p isn't silent in the middle of a word. Nephroptosis still gets its middle p pronounced; it's only the p that opens the word that disappears.

Syllable Stress in Greek- and Latin-Derived Terms

Most of the terms in this course put the stress on the syllable right before the suffix, unlike a lot of everyday English words, which lean on the first syllable instead.

• Arthritis puts the accent right before -itis: ar-THRY-tis, not AR-thry-tis.
• Osteoporosis does the same before -osis: os-tee-oh-puh-ROH-sis.
• Cardiology follows the pattern before -ology: kar-dee-AH-luh-jee.

Once you notice this, you can guess the stress on a term you've never said out loud just by finding the suffix and counting back one syllable.

Why Saying It Out Loud Actually Helps

Reading a term silently lets your eyes skip past the part that would trip you up. Saying it out loud forces you to commit to a pronunciation, which is exactly where the soft/hard letter and silent letter rules get tested. Say gingiva wrong out loud and you notice immediately, while a flashcard mistake can go unnoticed for weeks. The reverse holds too. Once you can say a term correctly, the spelling stops being a guessing game, because the sound tells you where the silent p goes and which vowel comes next. Read every new term in this course out loud at least once before you move on.

Worked Example

A typical chart line: "Patient with pneumonia, history of psychosis, seen by geriatric specialist."

Pneumonia: starts with the silent-p combination pn-, so the n carries the first sound: noo-MOHN-yuh.

Psychosis: starts with the silent-p combination ps-, so the s carries the first sound: sy-KOH-sis. Same stress pattern as osteoporosis, right before -osis.

Geriatric: g before e is soft, giving it a j sound to open on: jer-ee-AT-rik.

Try It Yourself

For each term, say whether the marked letter is soft or hard, or whether it opens on a silent letter, and give the reason.

Quick Recap

• C and g are soft before e, i, or y, and hard before a, o, or u.
• Pn-, ps-, and pt- at the start of a word drop the p; the same letter combinations mid-word keep it.
• Stress in most Greek- and Latin-derived terms falls on the syllable right before the suffix.
• Reading a term out loud catches mistakes that reading it silently lets slide.

Before Lesson 4, take five terms from the last two lessons and say each one out loud, checking the c/g sound and the stress against what you just learned. Reading direction and suffix-first translation are next.
