What does mat mean?
A mat is a removable piece of material laid on a floor, shelf, table, or other surface. Its purposes include protecting the surface, providing comfort, catching dirt, and sometimes defining an activity or area, as with an exercise mat or table mat. The word can also describe a tangled, compact mass of hair, vegetation, or fibers, and the verb “to mat” means either to cover something with a mat or to become tangled in this way. The familiar floor-covering sense is by far the most common in everyday English. Mat is especially useful because it names both the object itself and the process by which loose material becomes dense and difficult to separate.
A small removable covering placed on a floor or other surface to protect it, provide comfort, catch dirt, or serve a practical purpose.
"The entrance mat was covered with wet leaves."
Commonly used for smaller floor coverings, such as doormats, bath mats, exercise mats, and table mats.
A tangled or compact mass of hair, fibers, vegetation, or similar material.
"The sheep had a thick mat of wool around its neck."
This sense is less common than the floor-covering meaning and is often used attributively, as in a mat of hair.
To cover or protect with a mat, or to become a tangled, compact mass.
"Rain began to mat the grass together."
The intransitive use, meaning to become tangled, is especially common in descriptions of hair or vegetation.
The regular plural is used for individual floor coverings or other separate mat objects.
"The gym has several mats stacked against the wall."
The word mat began with the idea of something tangled together before it came to mean the familiar rug by the door.

Where does mat come from?
The word descends from Old English, where related forms referred to a tangled or matted mass. Its modern floor-covering sense developed as the word came to name a protective or decorative material placed underfoot. The English form belongs to a Germanic word family that also includes cognates such as German Matte and Dutch mat, both associated with an entangled mass or matting.
