The English suffix -ade is a small clue that points to a big sound. Whenever you see it, two things happen:
- The -ade is pronounced /ˈeɪd/ (rhymes with "made")
- The stress falls on the -ADE syllable
That is the entire rule. Once you trust it, dozens of words click into place.
The Core Rule
Words ending in -ade take primary stress on -ADE, pronounced /ˈeɪd/.
| Word | Stress | IPA |
|---|---|---|
| parade | pa-RADE | /pəˈreɪd/ |
| cascade | cas-CADE | /kæsˈkeɪd/ |
| lemonade | lem-on-ADE | /ˌleməˈneɪd/ |
| persuade | per-SUADE | /pərˈsweɪd/ |
| invade | in-VADE | /ɪnˈveɪd/ |
| blockade | block-ADE | /blɑːˈkeɪd/ |
| upgrade (verb) | up-GRADE | /ˌʌpˈɡreɪd/ |
| charade | cha-RADE | /ʃəˈreɪd/ |
| crusade | cru-SADE | /kruːˈseɪd/ |
Why It Works This Way
The -ade suffix entered English from French and Spanish (compare French "-ade" in limonade, parade, croisade). In those languages, the final syllable is stressed, and English imported the stress along with the spelling. Centuries later, the rule is still extremely consistent.
Quick Practice
The Vowel Reduction That Comes With It
Because -ADE pulls the stress, the syllables before it often weaken. The clearest pattern: middle vowels become schwa /ə/.
- lemonade → /ˌleməˈneɪd/ (the second "e" becomes /ə/)
- marmalade → /ˈmɑːrməleɪd/ (some speakers shift to mid-stress: MAR-ma-lade)
- serenade → /ˌserəˈneɪd/
For longer -ade words, English often gives a secondary stress to the first syllable so the word does not feel collapsed: LEM-on-ADE.
Real Exceptions
The rule is reliable, but a few common words break it. Most are loanwords from French where the stress was reanalyzed.
Stress on First Syllable
- marmalade /ˈmɑːrməleɪd/ - first-syllable stress is now standard
- renegade /ˈrenɪɡeɪd/ - stress on REN
- marinade /ˈmærɪneɪd/ (also /ˌmærɪˈneɪd/) - both are accepted
- accolade /ˈækəleɪd/ - first-syllable stress
The /ɑːd/ Variants
A few words that look like -ade are actually pronounced /ɑːd/ rather than /eɪd/:
- facade /fəˈsɑːd/ - keeps the French sound
- promenade /ˌprɑːməˈnɑːd/ in British English (American often /-ˈneɪd/)
- esplanade - varies between /-ˈnɑːd/ and /-ˈneɪd/
For these, learn each one individually.
Distinguish From Look-Alikes
Be careful: "made," "trade," "fade" are not -ade suffix words. They are one-syllable verbs that simply happen to end in -ade. The stress rule is irrelevant - the only syllable already takes the stress.
| One-syllable | -ade suffix |
|---|---|
| made /meɪd/ | parade /pəˈreɪd/ |
| trade /treɪd/ | cascade /kæsˈkeɪd/ |
| fade /feɪd/ | blockade /blɑːˈkeɪd/ |
Quick Summary
- -ade takes primary stress on -ADE, pronounced /ˈeɪd/
- Vowels before -ade often weaken to schwa /ə/
- Secondary stress often falls on the first syllable in longer words: LEM-on-ADE
- Exceptions to memorize: marmalade, renegade, accolade (first-syllable stress); facade /fəˈsɑːd/
- One-syllable words like made, trade, fade follow no special rule
Trust the rule, and a whole category of formal and elegant English words sounds correct from the first try.
