Grammar · Verbs

たいです, I want to

The pattern

[Verb stem] tai desu

Attach たい to the ます stem to say you want to do something. It then behaves like an い-adjective: たくないです for the negative.

The mistake to avoid

Only use it about yourself. Saying 田中さんは行きたいです claims to know another person's inner state, which Japanese avoids.
