Etch
Etch (pronounced: /ɛtʃ/) is a term often used in the medical field, particularly in the context of dentistry and surgery. It refers to the process of using an acid or other chemical substance to cut into the unprotected parts of a surface to create a design or pattern.
Etymology
The term "etch" is derived from the Dutch word "etsen," which was borrowed from the Old High German "azzen," meaning "to feed" or "cause to eat." This is a reference to the way the acid or other etching substance "eats" into the material it is applied to.
