mop

The word "mop" has several common meanings in everyday English. Most often, it means a cleaning tool used on floors and sometimes other surfaces. It usually has absorbent material, such as cloth strips, strings, or a sponge, attached to a long handle. You might mop the kitchen floor after dinner or use it to clean up a wet, dirty spot.

The word can also describe a thick, messy mass of hair. If someone has a lot of hair that looks full, untidy, or hard to control, you might say they have a "mop of hair." This use is informal and paints a clear picture of hair that looks heavy or a little wild.

As a verb, "to mop" means to clean with a mop, but it also means to wipe up moisture or liquid. You can mop up water from the floor, mop your brow with a towel, or mop up a spill before it spreads. In some contexts, "mop up" also means to finish cleaning up what is left.

So the word works well for household cleaning, for wiping away liquid, and for describing thick hair. It is a common, useful word with a few clear meanings that are easy to recognize from context.
