What is the origin of this metaphor?

Can you tell me the origin of the metaphor 'the tip of the iceberg'?

The metaphor 'the tip of the iceberg' originates from the fact that only a small part of an iceberg is visible above water, while the majority is hidden beneath the surface. It suggests that what we see is just a small part of a much larger issue.

That's interesting! When did it first come into use?

The phrase became popular in the early 20th century, particularly in the context of discussing complex issues, especially in psychology and social sciences.

Are there any other metaphors that have similar meanings?

Yes, similar metaphors include 'the surface of the problem' and 'the visible part of the issue,' both suggesting that there is more beneath what is immediately apparent.

Can you give me an example of how to use it in a sentence?

Sure! You might say, 'The financial troubles of the company are just the tip of the iceberg; there are deeper issues with management and strategy.'
