Etymology
.jpg)
The gnomon (sense 1) of this sundial in Taganrog, Rostov Oblast, Russia, is shaped like a triangular blade
A gnomon in geometry (sense 2)
Four is a figurate number as it can be represented by four dots arranged in a square. The next highest square is nine. Thus, the gnomon (sense 3) between four and nine is five (represented by the blue dots).
2=ǵneh₃Please see Module:checkparams for help with this warning.
Borrowed from Latin gnomon or French gnomon, from Ancient Greek γνώμων (gnṓmōn, “discerner, interpreter; carpenter's square; gnomon of a sundial; (geometry) gnomon”) (or directly from the Greek word), from γιγνώσκειν (gignṓskein),[1] present active infinitive of γιγνώσκω (gignṓskō, “to be aware of; to perceive; to know”), ultimately from Proto-Indo-European *ǵneh₃- (“to know”) (thus, the word is related to know).
The geometry sense (sense 3) is from the resemblance of the plane figure to a carpenter's square.[1] Similarly, a gnomon in mathematics (sense 4) is also shaped like a carpenter's square when depicted pictorially if the figurate numbers are squares.
