REF かどうか ·疑問詞ぎもんし+ か · てみます ›

1. 〜かどうか — whether or not

Formation: plain form + かどうか. な-adj and noun drop だ.

TypeExample
verb
い-adj
な-adj
noun

な-adj and nouns drop だ before か / かどうか — unlike と思おもいます (L21), which keeps it.

2. Question word + か — embedded wh-question

Choosing between them:

If the embedded question contains a question word (いつ · どこ · だれ · 何なに · どう) →か alone.

If it's a yes/no question → かどうか.

Main verbs that follow

わかります知しっています教おしえます調しらべます覚おぼえています忘わすれました聞ききます言いいます

The embedded clause is in plain form, and the subject inside takes が.

3. 〜てみます — try doing (to see how it goes)

Conjugates as Group II: てみる → てみたい → てみました → てみて.

Means "try it out and see" — not "attempt with difficulty" (that's 〜ようとします, later).

1. 〜かどうか — whether or not

A yes/no question can be swallowed into a bigger sentence. Put the question in plain form, add かどうか, and carry on.

QuestionEmbedded
JapaneseEnglish
I don't know whether I'll make the meeting.
Could you check whether this answer is right?
I don't know whether he's single.

Nouns and な-adjectives lose だ before か: ✕ · ○.

2. Question word + か — the embedded wh-question

When the question contains だれ, どこ, なに, いつ, どう, どれ, use plain か with no どうか.

JapaneseEnglish
Do you know when the meeting starts?
I don't know who's coming.
Please tell me where I can buy it.
I've forgotten what I should bring.
Please explain how to use it.
Question typeMarker
yes / no
question word

Both drop the question particle's politeness: ✕ — the embedded clause is always plain.

Main verbs that follow
知しっています分わかります調しらべます教おしえます聞ききます覚おぼえています確たしかめます心配しんぱいします

The particle before these verbs is normally dropped: is possible but stiff; is what people say.

3. 〜てみます — try it and see

て-form + みます. You are not "trying hard" — you are doing something once to find out what happens.

JapaneseEnglish
May I try this on?
I gave natto a try.
I'd like to try climbing Mt Fuji.
It might be no good, but I'll ask and see.

てみます is not "attempt but fail". For effort against difficulty, use or just the plain verb. And it cannot be used for something you have no choice about: ✕.

FormMeaning
do it once to find out
want to give it a try
give it a go
let's try it and see

4. Putting the two together

JapaneseEnglish
I'll taste it and see whether it's good.
I'll ring and ask whether there's space.
I'll look into how long it takes.
