I tried to start the old lawnmower this morning, but it's completely kaput.

After years of neglect, the old shop's kaputness became painfully obvious to every passerby.

My laptop is kaputt after the coffee spill.

By the time we reached the campsite, the portable stove was kaputz and we had to cook over the fire.

After the thunderstorm, the kaputsky radio wouldn't turn on.

I can't call anyone because my phone is kaputski.
