The -QUE Ending Rule: Why Unique, Antique, and Opaque All End in /k/

Published on April 30, 2026

If you've ever wondered why unique ends in a /k/ sound even though it's spelled with -que, you've found one of the most reliable spelling-to-sound rules in English. Every word ending in -que is a French loanword, and English borrowed both the spelling and the simple French rule: QUE at the end of a word equals /k/. Master this once and you'll correctly pronounce dozens of words.

The Rule in One Line

When a word ends in -que, the entire ending is pronounced as the single sound /k/. The Q, U, and E are all silent except for the K-sound they together represent. There are no exceptions in modern English vocabulary.

Why This Rule Exists

French uses -que to write the /k/ sound at the end of words (just as English uses -ck or -ke). When English imported these words, it kept the French spelling instead of respelling them as -k or -ck. The result: a French-looking ending that English speakers must learn as a unit.

Practice Words

The Pattern with Stress

Most -que words have a special stress pattern: the stress falls on the syllable just before the -que ending, and that syllable usually contains a long vowel.

  • uˈNIQUE /juːˈniːk/ — stress on NIQUE, long /iː/
  • anˈTIQUE /ænˈtiːk/ — stress on TIQUE, long /iː/
  • oˈPAQUE /oʊˈpeɪk/ — stress on PAQUE, long /eɪ/
  • techˈNIQUE /tɛkˈniːk/ — stress on NIQUE, long /iː/
  • bouˈTIQUE /buːˈtiːk/ — stress on TIQUE, long /iː/

This is the opposite of typical English stress, which usually falls on the first syllable. The French stress survived along with the spelling.

Short Single-Syllable -QUE Words

Short words don't move the stress, but the /k/ rule still applies and the vowel before is short:

  • plaque /plæk/ — short /æ/, just /k/ at the end
  • mosque /mɑːsk/ — the S is pronounced, but QUE is just /k/
  • clique /klɪk/ — short /ɪ/, then /k/
  • cheque /tʃɛk/ — British spelling for "check"

Common -QUE Words You Use

This list is short — less than fifty words in everyday English — but you meet many of them often:

  • technique, unique, antique, opaque, plaque, mosque, clique, oblique, baroque, grotesque, picturesque, mystique, physique, critique, communique, boutique, cheque (UK)

Don't Confuse -QUE with -QU at the Start of a Word

At the start or middle of a word, QU is pronounced /kw/ (queen, quiet, quick, request). It's only at the end of a word that QU+E collapses to a simple /k/. So:

  • queen /kwiːn/ — start of word: /kw/
  • quick /kwɪk/ — start of word: /kw/
  • unique /juːˈniːk/ — end of word: just /k/

Exceptions and Things to Watch

  • queue /kjuː/ — looks like it should follow the rule but actually rhymes with "you". The Q is /k/, the U adds /j/+/uː/, and the second UE is silent. This is the only common -QUE-like word that breaks the pattern.
  • masque /mæsk/ — old word for a costumed performance, follows the rule (just /k/).
  • Adjectives in -QUE often add -ly: uniquely /juːˈniːkli/, obliquely /əˈbliːkli/. The /k/ stays, then /li/.

Mini Practice

  1. "This is a unique opportunity to learn a new technique."
  2. "The antique was on display at a small boutique."
  3. "The plaque outside the mosque is in three languages."
  4. "Their clique has a very baroque sense of style."

Why This Rule Helps Your Speaking

Many learners over-pronounce these endings, saying "u-nik-yoo" or "an-tik-way". Native speakers hear these as foreign or comical. Once you internalise that -que = /k/, the entire family of words snaps into place at once.

Key Takeaways

  • Every English word ending in -QUE is a French loanword pronounced with a final /k/.
  • The Q, U, and E together form one sound: /k/. No vowel is heard at the end.
  • In multi-syllable -QUE words, the stress usually lands on the syllable before the ending and contains a long vowel.
  • QU at the start of a word is /kw/ (queen), but at the end of a word it collapses to /k/.
  • The only major exception is queue /kjuː/.
