Lesson Transcript#

Building たい From the ます Stem#

You already know the ます form of verbs from episode sixteen. 食べる becomes 食べます. The stem — the part before ます — is 食べ. To say you want to eat, take that stem and attach たい.

ます FormStem+ たいMeaning
食べます食べ食べたいwant to eat
飲みます飲み飲みたいwant to drink
行きます行き行きたいwant to go
見ます見たいwant to watch
読みます読み読みたいwant to read
買います買い買いたいwant to buy

It Conjugates Like an い-Adjective#

Here is the part that should feel like cheating — the word you just built ends in い, so it behaves as an い-adjective. Everything you learned back in episode twenty-five applies directly.

FormRuleExample
Positive+ たい食べたい (want to eat)
Negativedrop い, + くない食べたくない (do not want to eat)
Pastdrop い, + かった食べたかった (wanted to eat)
Past negativedrop い, + くなかった食べたくなかった (did not want to eat)

Nothing new to memorize. The whole system compounds.

Particle Flexibility: が or を#

Here is something most textbooks bury — with たい, you get to choose between が and を. Both are correct.

  • ピザが食べたい。 — が emphasizes the feeling. Pizza is what I am craving.
  • ピザを食べたい。 — を is more neutral. I want to eat pizza, matter-of-factly.

Same meaning, subtle difference in flavor. Native speakers use both. Pick whichever feels right in the moment.

Key Takeaway

たい attaches to the ます stem, and the result is an い-adjective. You already know how to make it negative (たくない), past (たかった), and past negative (たくなかった). One new piece unlocks four forms.
