have to read.’ Instead of the provisional of the negative

adjective -(a)nakereba, you can use the gerund of the
negative adjective -(a)nakute + the particle wa, with a

meaning something like ‘(as for) not doing… (as the topic).’
In these expressions of obligation, yomanakereba ‘if I do not

read’ and yomanakute wa ‘as for not reading’ are equivalent.
So you can say ‘I have to read (it)’ in any of the following

ways: Yomanakereba narimasen.

2. Yomanakereba dame desu.

3. Yomanakereba ikemasen.
4. Yomanakute wa narimasen.

5. Yomanakute wa dame desu.

6. Yomanakute wa ikemasen.

The first and last patterns (1 and 6) are more commonly
heard than the others. Forms ending -(a)nakute wa are often
pronounced -(a)nakucha in colloquial speech. They can end a

sentence with the same meaning as if followed by ikemasen.
