Origin
'Spectroscopy' is Latin + Greek for 'examining appearances' — analyzing light to reveal chemistry.
Definition
The branch of science concerned with the investigation and measurement of spectra produced when matter interacts with or emits electromagnetic radiation.
The Full Story
Latin/Greek19th centurywell-attested
A 19th-century scientific compound formed from two classical elements, both ultimately tracing to the same PIE root: Latin 'spectrum' (an image, a vision, an apparition — things that appear to the eye) from 'specere' (to look at, to observe), from PIE *spek- (to observe, to look carefully) + Greek 'skopein' (to look at, to examine carefully, to watch over), from 'skopos' (a watcher, an observer, a target), from the same PIE *spek-. ThePIE root *spek- is one of the great looking-roots of the family. Through the Latin branch it gave 'inspect' (to look into), 'expect' (to look out for), 'respect' (to look back upon), 'aspect' (a looking toward), 'species' (an appearance, a kind — things

'Spectroscopy' combines two different PIEroots for 'looking': Latin 'specere' (to look, from PIE *speḱ-) and Greek 'skopein' (to look at, from *skopos). Thescience of looking at what light looks like uses two different words for looking. Andthrough spectroscopy, astronomers can determine the chemical composition of stars
by how they look), 'specimen' (a thing for looking at), 'spectacle,' 'spectre,' 'speculum' (mirror), and 'speculate' (originally to observe from a watchtower, then to observe
a community), 'sceptic' (Greek 'skeptikos,' one who looks carefully and withholds judgment), and 'horoscope.' Spectroscopy — the analysis of spectra of light
in the 1860s by Kirchhoff and Bunsen. The word means literally 'the examination of appearances' or 'the careful watching of spectra,' combining both classical words for deliberate looking into a single compound that defines an entire field of chemistry, astrophysics, and atomic physics. Key roots: *speḱ- (Proto-Indo-European: "to look, to observe"), skopein (Greek: "to look at, to watch").
