Definition: A "swan dive" is a type of dive where a person jumps into the water by arching their back and stretching their arms out to the sides. It looks graceful, similar to how a swan moves.
In more advanced contexts, "swan dive" can also refer to a dramatic fall or drop in something, like a stock price or a person's fortunes, although this is less common.
While "swan dive" primarily refers to the diving technique, in informal or metaphorical contexts, it can describe any graceful or dramatic entry into a situation.
There are no direct idioms or phrasal verbs specifically related to "swan dive," but you could use the phrase "take the plunge" which means to make a decision to do something risky or to enter a new situation, similar to how one might jump into water.
The term "swan dive" is a beautiful way to describe a specific diving technique that is not only about the act of diving but also conveys a sense of elegance.
