In plain English: Grounds are the dry, crushed coffee beans used to make hot drinks.

Usage: Use "grounds" to refer to the solid residue left behind after filtering a liquid, such as coffee grounds remaining in a filter. Do not use this term for land or reasons, as those require different spellings like "ground" or "grounds" with an 's' only when pluralized appropriately for location or cause.
Third-person singular simple present indicative form of ground
"The dog grounds its paw firmly on the muddy floor before jumping up to catch the ball."
In plain English: To ground something means to make it stable so it won't move or fall over.
"He grounds his children every time they break the rules."
Usage: Do not use "grounds" as a verb; it is simply the third-person singular present tense of "ground," used only when referring to actions performed by he, she, or it. Since the word has no other common everyday meaning as a verb, avoid using it to mean anything else entirely.
The word grounds comes from the Old English noun grund, which originally meant "bottom" or "foundation." It entered modern usage to describe the earth beneath one's feet as well as the supporting basis for an argument.
