The pronotum (Biology) is a prominent plate-like structure that covers all or part of the thorax of some insects. The pronotum covers the dorsal surface of the thorax.
The word can be split in two parts: pro + notum.
pro is reasonably unambiguous, but the notum part is frustrating.
1: word-forming element meaning "forward, forth, toward the front" (as in proclaim, proceed); "beforehand, in advance" (prohibit, provide);
2: The common modern sense "in favor of, on behalf of, supporting" (pro-independence, pro-fluoridation, pro-Soviet, etc.) was not in classical Latin and is attested in English from early 19c.
- -sḱéti Proto-Indo-European (ine-pro)
*ǵn̥h₃sḱéti Proto-Indo-European (ine-pro) To recognise.
(Wikipedia) *gnōskō Proto-Italic (itc-pro) Know, get to know.
It has the root *gno*, same as in "ignore"
νῶτον (noton) From Proto-Indo-European *not- (“rear, buttock”);
related to Latin natis (“rump”).
a combining form meaning “the back,” used in the formation of compound words:
eg. notochord [Greek nōton, nōtos back + Latin chorda cord]
eg. notodont adj. [Gr. notos, back; odous, tooth]
What is the coinage pronotum supposed to mean? The usage and origin of notum leaves me begging for a sensible literal meaning of the word, on whether it comes from "-notus" or "-noton".
Is it supposed to be "the notable supporting structure", or "the structure preceding the back", or something else?
(Extra: there are also the genera "Lanthonotus" and "Camponotus" - do they use the same notus suffix as in pronotum?)
