Conjugating い-Adjectives to Conditional Form (〜ければ)

    • Adjective
    • Conjugation Form
    When an い-adjective ends in 〜ければ, it tells us that the word is in the conditional form. We use this form in the same sort of situations when we would use "if" or "when" in English.

    What Is the Conditional Form of い-Adjectives?

    The conditional form of い-adjectives ends in 〜ければ. To get this form, simply replace the 〜い on the end of an adjective with 〜ければ to give a rough equivalent of "if" or "when" in English:

    難し + ければ = 難しければ

    There is one exception to this rule, and that is the irregular adjective いい, which changes to よければ.
