protrude

If something protrudes, it sticks out beyond the surface around it. Think of a rock sticking out of smooth sand on a beach, or a nail protruding from a board. It is not just visible; it goes outward in a noticeable way. The word is most often used for physical things.

The word often suggests that something has pushed past a line or surface. A splinter protruding from your finger needs to be removed. A pipe might protrude from a wall. In some cases, people also use it more loosely for something that stands out, but the physical sense is the main one.

To protrude means to extend outward beyond a surface, edge, or boundary. In simple terms, it means to stick out in a way that can be clearly seen. For example, the roots of an old tree may protrude from the soil, or a shelf may protrude from a wall. In each case, part of the object goes beyond the surface around it.

The word is mainly used for physical things. A balcony can protrude from a building. A branch can protrude through a fence. A bone can protrude through the skin in a serious injury. These examples all share the same idea: something crosses the usual limit and remains visibly outside it.

It does not always suggest a problem. Something can protrude only a little, or it can stick out a lot. Sometimes that is accidental, like a wire protruding from a broken machine. Sometimes it is deliberate, like part of a building protruding to create a bold shape.

People do sometimes use the word in a more figurative way for something that stands out, but that use is less central. Most of the time, if something protrudes, you can imagine it physically pushing past a surface and being easy to notice.
