✕Common Mistakes

  • Quel est le plus économique ?

    “Quel” asks about a noun, not “which one”. Use “Lequel” when the noun is already understood.

  • Lequel est plus économique ?

    Do not drop the article “le” before the superlative; it is required in French.

  • Lequel est le plus économiquement ?

    Avoid using the adverb “économiquement” here; the adjective is needed for the superlative.

Cultural Tip

In French, the superlative is formed with “le/la/les + plus/moins + adjective”. The pronoun “lequel” must agree in gender and number with the noun it replaces, so for a feminine singular you would ask “Laquelle est la plus économique ?”. In spoken French, the liaison between “le” and “plus” (le + plus → /lə plyz/) is optional but common in careful speech.
