Understanding the Idiom: Vanish into Thin Air

The question asks for the most appropriate meaning of the idiom "Vanish into thin air". Idioms are phrases or expressions whose meaning cannot be deduced from the literal meaning of its individual words. Let's break down this specific idiom.

The phrase "Vanish into thin air" paints a picture of something disappearing completely, leaving no trace behind. Imagine smoke or mist dissolving so thoroughly that it becomes part of the air and is no longer visible.

Now, let's look at the given options and see which one matches this understanding:

• Option 1: Permanently mix
  This option suggests blending or combining things together in a way that is lasting. This does not relate to the idea of disappearing.
• Option 2: Totally dilute
  Dilution means making a liquid weaker by adding another liquid, usually water. While something might become less concentrated, it is still present. This is not the meaning of "vanishing".
• Option 3: Completely disappear
  This option directly means to become invisible or cease to exist in a particular location, leaving no trace. This aligns perfectly with the image conveyed by "vanishing into thin air".
• Option 4: Perpetually postpone
  To postpone means to delay an event or task. Perpetually means doing it indefinitely. This is related to timing and delay, not to disappearing.

Comparing the options, the meaning that most accurately describes something that disappears utterly, without leaving any sign, is "Completely disappear".
