Volitional form (意向形いこうけい)

GroupRuleExample
1 godanu-row → o-row + う
2 ichidanる → よう

This is the plain equivalent of ましょう: 行いきましょう →行いこう.

1. Volitional alone — casual "let's"

2. 〜(よ)うと思おもっています — intention

FormNuance

have been intending for a while

〜と思おもっています can describe a third person's intention; 〜と思おもいます generally cannot.

3. 〜つもりです — firm plan

FormExample
dict + つもり
ない + つもり

Stronger and more settled than 〜ようと思おもっています.

4. 〜予定よていです — scheduled

FormExample
dict +予定よてい
noun + の+予定よてい

予定よてい= fixed on a calendar, often decided by someone else. つもり = your personal resolve.

5. まだ 〜ていません

— haven't decided yet (but intend to).

Making the 意向形いこうけい (volitional)

The volitional is the plain-form twin of ましょう. Build it from the dictionary form.

GroupRuleExampleVolitional
I (godan)final う-row kana → お-row + う
II (ichidan)drop る, add よう
IIIirregular
PolitePlain volitional

The rule is the same vowel shift as the ない-form but with お instead of あ: / . Group II adds よう, not just う — ✕ · ○.

1. Volitional on its own — casual "let's"

JapaneseEnglish
Let's take a break.
Shall we head home soon?
Want me to help?

Plain volitional is casual. To a teacher, a client or anyone you would use です with, say — never .

2. 〜(よ)うと思っています — what I intend to do

Volitional + と思おもっています reports a decision you have already made and are still holding.

JapaneseEnglish
I'm thinking of studying in Japan next year.
I intend to exercise every day.
I'm planning to buy a car.
FormWhat it implies
I decided just now, as I speak
I decided a while ago and still intend it

Only ています works for someone else: ○. You cannot read a third person's mind at the instant of deciding, so ✕ in this pattern.

3. 〜つもりです — a firm plan

Attaches to the plain dictionary form (not the volitional).

JapaneseEnglish
I intend to go home and teach Japanese.
I'm going to quit smoking.

Two negatives, two strengths:

FormStrength
I intend not to do it
I have no intention of doing it — flatly refuses

✕. The volitional never meets つもり: ✕ · ○.

4. 〜予定よていです — it is on the schedule

Follows the dictionary form, or a noun + の. Use it for arrangements that exist outside your own head: flights, meetings, ceremonies.

JapaneseEnglish
I'm scheduled to go to Osaka next week.
The meeting is scheduled from 3.
I'm due to return home next month.

5. まだ 〜ていません — not decided / not done yet

JapaneseEnglish
"Have you had lunch?" "No, not yet."
I haven't decided yet.
I haven't bought the ticket yet.

Answer 「もう〜ましたか」 with or — never , which means "I didn't do it (and that's over)".

6. The certainty ladder

WeakestFormReads as
1I want to
2I'm thinking of / I intend to
3I've made up my mind
4it's booked, it's on the calendar
5I'm doing it

Step 1 carries a restriction the other four do not. states your own desire — for anyone else you need , or a hedge: . ✕ · ○. This is the same rule the app gives you for in L13, and it applies to たい just as hard.

Asking is a different matter: is fine to a friend, because the subject is the person in front of you. To a superior it is still intrusive — or instead (L13).

group II adds よう
つもり takes the dictionary form
third-person intention needs ています
