What does "microscope" refer to in terms of size?

The term "microscope" primarily refers to an instrument used to magnify small objects that are typically not visible to the naked eye. In this context, it is relevant to denote that the items observed under a microscope are indeed small, whether they are cells, bacteria, or other microscopic entities. The essence of a microscope's purpose—enabling visualization of minuscule details—underlines its association with smallness. Consequently, saying that "microscope" refers to size aligns with the standard understanding of the tool and its application in scientific observation.
