Word: Mirror Image
Definition: A "mirror image" is a noun that refers to an exact likeness of something, but with the left and right sides reversed, just as you would see in a mirror. For example, if you look into a mirror, the reflection shows you with your left side appearing on the right.
In more advanced contexts, "mirror image" can refer to concepts in mathematics, art, or even behavior. For instance, in psychology, one might say, “Her actions were a mirror image of her thoughts.”
While there are no direct idioms or phrasal verbs that use "mirror image," you might encounter expressions like "the mirror of society," which reflects on how society reflects certain truths or issues.
In summary, "mirror image" is a versatile term that can describe both physical reflections and abstract similarities. It's most commonly used in contexts where things are alike but reversed or different in arrangement.
