* Silent: Means making no sound, or not speaking.
* Still: Means quiet or motionless, or remaining in a particular state or position.
Here are some examples to illustrate the difference:
* Silent: The library was completely silent.
* Still: The water in the lake was still and calm.
While you might say "The room was still" to indicate that it was quiet, it's not the same as saying "The room was silent." The room could be still even if there is a faint sound, like a ticking clock.
In summary: While "still" can sometimes imply quietness, it is not a synonym for "silent." They have different meanings and should be used accordingly.
