Someone something levitate they appear to rise and float in the air without anything to support them.

If you neglect something you fail to take care of it properly.

If you stifle something that is happening you force it to stop

Something that I has gone astray has gone missing on its way somewhere

If you have an alibi for something you can prove it was not your fault or you were somewhere else when it happened

Something that is an enigma is mysterious and difficult to understand

A daring action can be called an escapade

To be notorious mean to be well known for something bad
