I found some junk in the attic.

The junk sailed gracefully across the sea.

All their old computers had been junked.

I try to avoid eating junk food because it is high in calories but low in nutritional value.

I always throw away junk mail without even opening it.

I bought a junker car for a cheap price.

Junker is a German term.

I enjoyed a delicious junket for dessert.

They organized a junketing to celebrate their success.
