Etymology
Origin of magnification
First recorded in 1615–25, magnification is from the Late Latin word magnificātiōn- (stem of magnificātiō ). See magnify, -fication
Explanation
Magnification is the process of making an object appear much larger than it really is. You might use magnification to inspect a rare penny, or even a zit. You decide. Some small objects, like cells, require magnification to be seen at all. Other things, like distant planets, are so far away that you need the magnification of a telescope to get a good look at them. Binoculars use magnification so you can see the details of birds close-up, and reading glasses use magnification for reading small print. Magnification comes from the Latin word magnificare, "esteem greatly" or "make much of."
