  2. (ては~) it's bad if...
    宿(しゅく)(だい)をしなくてはいけない
    Shukudai o shinakute wa ikenai.
    I have to do my homework.

Usage notes edit

The “it's bad if …” sense is similar to ならない (naranai) or だめ (dame), but appeals to morals instead of rules. ならない (naranai) is used for something you're not allowed to do, and いけない (ikenai) is used for something that you shouldn't do because it brings about an unwanted result. However, this doesn't mean that いけない (ikenai) (e.g. in ~てはいけない (~te wa ikenai)) makes it a request instead of a demand.
