Lesson 6
Conditional Forms


To make positive conditionals, replace the final i with kereba in true adjectives, and add nara to quasis:

  • Yasukereba kaimashou. (If it's inexpensive, let's buy it.)
  • Soto wa atsukereba detakunai. (I don't want to go out if it's hot outside.)
  • Inu wa byouki nara, juui ni tsurete ikou. (If the dog's sick, let's take him to the vet.)

Note: Naraba can also be used after quasi-adjectives, but nara is more common.

For negative conditionals, use ku nakereba (the negative-forming ku nai + kereba) with true adjectives, and de nakereba (the negative-forming de nai + kereba) with quasis:

  • Ashita wa samuku nakereba ikimashou. (If it's not cold tomorrow, let's go.)
  • Kono pasokon ga hoshiku nakereba, betsu no mise ni ikimashou. (If you don't want this computer, let's go to another store.)
  • Mise no basho wa benri de nakereba, kyaku ga sukunai deshou. (If the store isn't in a convenient location, it probably won't get many customers.)
