Etymology

It is formed from English microscope + -ic.[2][3][4][5] The noun microscope (1650s) comes from Italian microscopio, apparently from New Latin microscopium, formed from micro- and -scopium as in telescopium.[2][4] The OED compares the post-classical Latin adjective microscopicus, recorded by 1651, and French microscopique (1733), Italian microscopico (before 1730) and German mikroskopisch (1776);[2] Merriam-Webster and Webster's Third derive the English word from that Latin adjective.[6][7] The longer form microscopical is recorded earlier, from 1663.[2][4]

Earliest recorded meaning

Able to magnify or reveal things as a microscope does: before 1680, in Butler's Genuine Remains.[2] Merriam-Webster dates the word to about 1672,[6] Dictionary.com to 1670–80,[8] and Etymonline only to 1732, in the sense "pertaining to or functioning as a microscope".[4]

Semantic evolution

In the 18th century the word was used of an eye or instrument with the power of a microscope, as in Pope's question in the Essay on Man (1733), "Why has not Man a microscopic eye?";[2][5] this use is obsolete.[2] From 1735 it meant relating to or done with a microscope;[2] from 1767 it was used of an investigation carried out as if with a microscope, in minute detail.[2][9] The sense "too small to be seen without a microscope" is recorded from 1742,[2][4] and it was extended from 1798 to anything very small or insignificant.[2][5]
