What the use of a word or phrase to suggest two more meanings at same time?

The use of a word or phrase to suggest two or more meanings at the same time is called double entendre.

Here's a breakdown:

* Double refers to the two meanings.

* Entendre comes from the French word "entendre," which means "to understand."

Examples:

* "I'm looking for a good time." (Could mean a fun evening or a sexual encounter)

* "He's a real catch." (Could mean he's desirable or he's good at fishing)

* "That's a nice tie." (Could mean the tie is aesthetically pleasing or it's a gift from someone special)

Double entendres are often used for:

* Humor: To create a playful or suggestive tone.

* Ambiguity: To create uncertainty or intrigue.

* Irony: To convey a contrasting meaning.

* Subtlety: To convey a message in a subtle or indirect way.

It's important to note that the intended meaning of a double entendre can be subjective, and the effectiveness of the device depends on the context and audience.
