The -cy Ending: Why Democracy Is de-MOC-ra-cy and Urgency Is UR-gen-cy

Say democracy aloud. Where did your voice get louder: "DEM-oh-cracy", "demo-CRA-cy", or "de-MOC-ra-cy"? The correct answer is the third one. Words ending in -cy are some of the hardest to stress, because they are long, they are often abstract, and the stress looks random. It is not random. There is one simple pattern: the last two syllables are weak, and the stress lands on the syllable just before them, or one step further back when that syllable is weak too. The ending itself is short and quiet: /si/.

This rule covers dozens of useful words: democracy, urgency, accuracy, fluency, privacy, emergency, frequency, currency, tendency, agency, policy, literacy. Learn it once and you can stress them all with confidence.

The Rule in Short

1. -cy is pronounced /si/. The c is soft (it sounds like s) and the y is a short /i/ sound, as at the end of happy. There is no "k" and no /aɪ/.
2. Skip the weak tail, then stress the syllable before it. The tail is -a-cy, -en-cy or -an-cy: de-MOC-ra-cy, UR-gen-cy, PRIV-a-cy, e-MER-gen-cy, di-PLO-ma-cy.
3. If that syllable is weak too, jump back one more: AC-cu-ra-cy (not ac-CU-ra-cy), LIT-er-a-cy, IN-ti-ma-cy, AD-e-qua-cy. It is the same "skip the weak syllable" logic as PRES-i-dent.
4. The vowel before -cy is weak. In -acy, -ency and -ancy, the a/e is a schwa: accuracy /ˈækjərəsi/, urgency /ˈɝdʒənsi/, vacancy /ˈveɪkənsi/.
5. Two-syllable -cy words stress the first syllable: FAN-cy, JUI-cy, SPI-cy, MER-cy. These are short, and the first vowel is full.
6. When the related word is different, the stress moves: DEM-o-crat → de-MOC-ra-cy, DIP-lo-mat → di-PLO-ma-cy, BUR-eau-crat → bu-ROC-ra-cy.

Why It Works

-cy behaves like -ology and -graphy

English puts the stress early in long words that end in a weak -y tail: biology, geography, democracy, diplomacy all have the stress on the third syllable from the end. The pattern comes from Greek and Latin words absorbed into English with a short, weak ending. Words like accuracy go one syllable further back only to avoid stressing a weak syllable. If you already know the antepenult rule for -ology and -ography, you only need to add -cy to the same family.

Related words show you the stress

A useful trick: many -cy nouns come from adjectives that end in -ent, -ant or -ate. The stress of the adjective often tells you the stress of the noun: urgent → urgency, frequent → frequency, fluent → fluency, accurate → accuracy, private → privacy, literate → literacy. Where the stress does change (democrat → democracy, diplomat → diplomacy), the "syllable before the weak tail" rule is your safety net.

Why the c sounds like s

In English, the letter c before e, i, or y is soft (/s/). That is why cycle, city and cent start with /s/, and why -cy at the end is /si/. Read more in our hard and soft C rule.

Pattern Table

Exceptions

• Two-syllable words (fancy, mercy, spicy, juicy, lacy) obviously stress the first syllable, so they do not follow the third-from-end rule.
• Words from -crat and -mat roots (democracy, bureaucracy, aristocracy, diplomacy) always put the main stress right before the -ra-cy or -ma-cy tail: de-MOC-ra-cy, bu-ROC-ra-cy, a-ris-TOC-ra-cy.
• Policy /ˈpɑləsi/ is stressed on POL. Do not confuse it with police /pəˈlis/, which is stressed on the second syllable.
• Privacy has two accepted vowels: /ˈpraɪvəsi/ (more American) and /ˈprɪvəsi/ (more British). Both are correct.
• Bankruptcy /ˈbæŋkrʌptsi/ and prophecy /ˈprɑfəsi/ are stressed on the first syllable. Note that the verb prophesy (with s) is /ˈprɑfəˌsaɪ/ and ends in /aɪ/. Spelling decides: -cy for the noun, -sy for the verb.
• Efficiency, deficiency, proficiency have -ci- before -ency, which gives /ʃ/: /ɪˈfɪʃənsi/. The stress sits on the syllable just before the /ʃ/.

Common Learner Mistakes

• Stressing the ending: "democra-SEE" or "urgen-SEE". The ending is quiet.
• Spanish and Portuguese speakers carry over the stress of democracia, urgencia, fluencia, agencia, emergencia: de-mo-CRA-cia puts the stress on the second to last syllable. English puts the stress earlier: de-MOC-ra-cy.
• French speakers carry over final stress from démocratie /demɔkʁasi/ and urgence, so they say "democra-CEE". Hold back the stress to the earlier syllable.
• German speakers know Demokratie with stress on the last syllable (Demokra-TIE), so they often say "democra-SEE". English stresses MOC.
• Reading c as /k/: "democra-ky". The letter c before y is always /s/ in this ending.
• Full vowels in the weak syllables: "accu-RAY-cy" or "urgen-SEE". The a and e are schwa.

How to Practice

1. Cross out the weak tail. Cover -a-cy or -en-cy with your finger. Stress the syllable just before it, or one more back if that one is weak.
2. Clap the pattern: LOUD-soft-soft for URgency, AGency, FLUency, soft-LOUD-soft-soft for deMOCracy, diPLOmacy.
3. Whisper the ending. Say "sy" as a fast, light syllable, like the end of happy.
4. Start from the adjective. Say urgent, then urgency. Notice that the first syllable stays strong.
5. Use a sentence. "In an emergency, speed and accuracy matter." Slow it down, then speed up.
6. Record yourself and compare to the audio on the cards.

Practice

Practice Sentences

• In a democracy, privacy and accuracy matter.
• The agency treated the emergency with urgency.
• Fluency grows with the frequency of practice.
• The policy changed the currency and the tendency.
• Diplomacy needs patience, efficiency, and literacy.
• There is a vacancy at the agency, but no urgency.

Quick Summary

• -cy is /si/, with a soft c and a short, weak ending.
• Skip the weak tail (-a-cy, -en-cy) and stress the syllable before it: de-MOC-ra-cy, UR-gen-cy. If that syllable is weak, go back one more: AC-cu-ra-cy.
• The vowel before -cy is schwa: accuracy /ˈækjərəsi/.
• Check the related adjective (urgent, frequent, fluent, accurate) to confirm the stress, but trust the tail rule for democracy, diplomacy.
• Exceptions: two-syllable words (fancy, mercy), privacy (two accepted vowels), and policy (not related to police).
