Te Form + wa ikenai, wa ikimasu
If you hear いけない ikenai alone it means "You must not do that...:, "Don't do that!". In a shopping center where mothers and kids are together and you're bound to hear "ikenai!".
Plain ikenai will be heard more often than ikemasen.
- Ikenai! (No! Don't!)
- Ikenai! Joushaken o wasurete shimaimashita! (Oh, no! I forgot my ticket!)
- Ikenai! Kimiko wa kasa o motte iku no o wasuremashita! (Oh, no! Kimiko forgot to take her umbrella!)
