Some adjectives break all the rules. They don't agree at all. They don't change. They don't take an 'e' in the feminine, and they don't take an 's' in the plural. They are, in fact, invariable.

chic (trendy, stylish) marron (brown)
snob (snobbish) orange (orange)
sympa (kind, nice) cerise (cerise, cherry colored)
extra (cool, great) olive (olive)
bon marché (cheap) kaki (khaki)

Here are some examples of these invariable adjectives in use:

  • Ma mère est plus chic que mon père.
  • Mes voisins sont très snob; ils ne disent jamais bonjour.
  • Ma soeur cadette est très sympa.
  • Mon père porte des chemises marron, des chaussures marron,
    des costumes marron, et des cravates orange.
  • Au printemps, ma tante sort sa longue robe orange et sa collection de chapeaux cerise qu'elle adore tant.


So why do these adjectives not agree with their nouns?
