Plateux or Plateaux: Which French Plural Is Correct
“Plateaux” is the correct French plural of “plateau.” The singular ends in –eau, so add an –x instead of an –s.
English writers often stick “-s” on everything, so “plateux” pops up as a slip. It looks tidy, but French spelling has its own quirks.
Correct Spelling and Rules
Words ending in –eau take –x in plural: one plateau, many plateaux. No silent letters change.
Common Mistakes
Typing “plateux” or “plateaus” ignores French grammar. Keep the –eau and swap –x for the plural.
Is “plateaux” only for French texts?
No; English borrows the plural when discussing geography or cuisine.
Does pronunciation change?
The final –x is silent; “plateaux” still sounds like “plateau.”
