Here's a breakdown of its meaning:
* "It": Refers to the subject being discussed.
* "Speaks": Implies that the subject is communicating its own message without needing words.
* "For itself": Indicates that the subject is capable of being understood on its own merits.
Examples:
* "The evidence speaks for itself. There's no denying the suspect's guilt." The evidence is so clear that it doesn't need any further explanation.
* "The design of the building is stunning. It truly speaks for itself." The building's beauty is self-evident.
* "The success of the company speaks for itself. They've consistently exceeded their goals." The company's accomplishments are a clear indicator of its success.
In essence, "it speaks for itself" is a way of saying:
* "The evidence is clear."
* "It's obvious."
* "You don't need to explain it further."
However, it's important to note that this phrase can sometimes be used to avoid providing a more detailed explanation or justification. It can be a way of brushing something aside without addressing any potential counterarguments.
