Grammar › Intention › つもり
つもり
"I intend to." A settled personal plan you've already made in your head — firmer than "maybe", more considered than a spur-of-the-moment idea.
The short version
Put a plain-form verb in front of つもり, then finish with だ/です. It states a decision you've already reached: 行くつもりです = "I intend to go". For "intend not to", use the negative verb: 行かないつもり.
つもりです — a plan you've made
Use it for something you've decided and mean to do. It's about your own settled intention, so it's mostly used for yourself (or when reporting someone else's stated plan).
つもりはない — no intention
Attach つもり to だ→ない, and you get "I have no intention of…" — a firm way to rule something out.
つもりだった — meant to, but…
In the past tense, つもりだった often means an intention that didn't pan out — "I was going to, but…". The unspoken "but it didn't happen" is doing a lot of work.
