i-adjectives and their conjugation

i-adjectives with 2 i's in the end like hoshii (to want) can be conjugated in various ways.

1. For present tense, just leave it as it is.

So it would just be hoshii desu.

2. For past tense, replace the last i with -katta (desu).

So it would be hoshikatta (desu) - (wanted).

3. For past tense negative, replace the last i with -kuarimasen deshita.

So it would be hoshikuarimasen deshita (did not want).

4. For present negative, replace the last i with -ku arimasen.

So it would be hoshikuarimasen (not want/do not want).

It can also be conjugated in the casual form. This only applies to the negative form only.

1. For present negative (casual form),

replace the last i with -ku nai (desu).

So it would be hoshiku nai (desu) - (not want/don't want).

2. For past tense negative (casual form),

replace the last i with -kunakatta deshita.

So it would be hoshikunakatta deshita (didn't want).
