ようと思う

ようと思おもう means “thinking of doing”. Used with a verb in the volitional form (よう).

つもり

Means “intend to”.

Example

明日ゲームセンターに行くつもりはない。 I don’t plan to go to the arcade tomorrow.

つもりだった・つもりなのに

Used to express that someone thought they did something.

Example

リンゴを買うつもりだったけど。 I was planning to buy apples… (it was my intention, but I changed my mind)

つもりで

V (た)

N + の

+ つもりで

Means “with the intention of doing”.

Example

よてい
