* Idioms are fixed expressions: They have a meaning that is different from the literal meaning of the words. For example, "kick the bucket" means "to die," not to literally kick a bucket.
* Changing the words changes the meaning: If you change the words of an idiom, you will likely change the meaning entirely. It will no longer be the same idiom.
* It's better to paraphrase: Instead of trying to change an idiom, it's better to paraphrase it using your own words. This will help you to communicate the same meaning without relying on the idiom itself.
Here's an example:
* Idiom: "It's raining cats and dogs."
* Paraphrase: "It's raining very heavily."
When is it okay to change an idiom?
* Creative writing: In some forms of creative writing, you might intentionally change an idiom to create a unique effect. However, this should be done carefully and with a clear understanding of the original idiom's meaning.
* Humor: You can sometimes use altered idioms for humor, but again, it's important to ensure the meaning is clear and the humor is intentional.
In general, it's best to stick with the original form of an idiom unless you have a good reason to change it.
