Cut
In short
A cut is a break in the skin or body tissue caused by a sharp object. It often results in bleeding and requires cleaning to prevent infection.
In plain words
When something sharp like a knife or glass touches your skin, it slices the surface. This creates an open wound. You usually need to stop the bleeding and cover it with a plaster.
A simple example
If you are chopping vegetables and the knife slips, you might get a small cut on your finger. You would wash it with water and apply a bandage.
Why it matters
Even small cuts can let germs into your body. If not treated properly, they can lead to painful infections or scarring.
Easy to mix up
Do not confuse a cut with a bruise, which is damage under the skin that does not break the surface.
