たい (tai) — sensushi

Related patterns5

Similar

がほしい
Both work as い-adjectives and mark what's wanted with が. たい wants an action, off the ます-stem, and ほしい a thing after a noun.

Lookalikes

たがる
たい states the speaker's own urge (行いきたかった). Talking about someone else needs たがる instead (行いきたがった), which also prefers を where たい leans on が.
ますように
たい names something you can go and do yourself (試験しけんを受うけたい). ますように wishes for something nobody can control (受うかりますように).
てほしい
たい, off the verb's ます-stem, wants to act yourself. てほしい, off the て-form, wants someone else to act (手伝てつだいたい offers help, 手伝てつだってほしい requests it).
てもらいたい
たい alone can never voice a wish about someone else's action (聞ききたい). もらいたい adds て to voice one instead (聞きいてもらいたい).

Notes

たい is an い-adjective, so its object leans on が (水みずが飲のみたい), though を is standard too.
Naked たいです states a want more directly than politeness usually
allows; たいと思おもいます cushions it.
