Hi,
what are the differences between "to dive" and "to plunge"?
Thanks

Hi Ana, as far as I can see, they are synonyms. The English-Dutch dictionary translates both with 'duik' , but in a trilingual dictionary I find this:
Scuba diving Duiken Mergulho
immerse; plunge duiken submergir

Is it of any help?

Hi, Anapaula.

Darbanville is absolutely correct. They are synonyms. However, we use them many ways.

Plunge can also refer to a rapid decline in value. "The stock market plunged this morning"

We can also say "take the plunge" which means to commit yourself to a course of action.

Dive and plunge are often used figuratively and interchangeably. In my opinion, "plunge" tends to have more power or weight than "dive." I hope this helps!

The verbs means the same thing, there is very little difference in use.

if you are talking about a person doing sport, call it diving. "My hobby is scuba plunging" sounds silly.

On the other hand, call it plunging when an object is being pushed down into liquid. I have a plunger in my coffee pot and another under the kitchen sink. "I need to buy a new diver to unblock the toilet" sounds silly too.

Thank you all. I guess I got some of the subtleties of these two synonyms.
