Across
* Movement on a surface: "Across" typically indicates movement over a surface, often in a straight line. It implies movement from one side to the other of something, often flat.
* *Example:* "He walked across the street." (He moved from one side to the other)
* Movement over a distance: It can also indicate movement over a distance, but not necessarily over a specific surface.
* *Example:* "We drove across the country." (We traveled a long distance)
Through
* Movement into and out of: "Through" describes movement *into* something and *out* the other side. It implies passing *within* the object, not just on its surface.
* *Example:* "He walked through the door." (He entered the room)
* *Example:* "The train went through the tunnel." (The train traveled within the tunnel)
* Movement among or between: "Through" can also mean movement among or between things.
* *Example:* "We drove through the forest." (We traveled among the trees)
Here's a helpful way to remember the difference:
* Across is like a bridge - you travel over it, not through it.
* Through is like a tunnel - you travel inside it, not just on its surface.
Here are some examples to clarify:
* Across: She walked across the room, across the bridge, across the desert.
* Through: She walked through the door, through the tunnel, through the forest.
Remember, context is key! In some cases, the two words can be interchangeable. For example, you could say "The train went across the country" or "The train went through the country" and both would be correct.
