Preposition usage

Should it be "the snake moved THROUGH the grass" or the snake "moved IN the grass" ?I have seen "moved in the grass" used in some places but I feel like it depends on the density of the grass. Which one's correct ? An explanation would be helpful too.

Solution 1:

Without context, I would say "moved through the grass" implies direction, meaning the snake moved purposefully from point A to point B. To me, "moved in the grass" means that the snake is moving but with no intent on a particular direction.

Both are correct, it just depends on the context.

Solution 2:

It depends on what you want to emphasize.

The snake moved THROUGH the grass.

This sentence emphasizes the motion of the snake.

The snake moved IN the grass.

This sentence emphasizes the location of the snake.

Why use one or the other? It depends on the context of the sentence. If one didn't know HOW the snake moved, one would likely use the first, and if one didn't know where the snake moved, the second.

Q The snake in the grass did what?
A It moved through the grass.
or
Q The snake was found. How?
