[ Etymonline for 'predicate (n.)] ... from prae- "forth, before" (see pre-) + dicare "proclaim," from stem of dicere "to speak, to say" (see diction). Grammatical sense is from 1630s. ...
[ODO:] {noun} {Grammar} 1. = The part of a sentence or clause containing a verb and stating something about the subject
[OED:] 2.a. = {trans. Logic.} To state or assert (something) about the subject of a proposition
In logic, English, and French, the subject usually precedes the predicate. Per contra, the prefix prae- (in 'predicate') suggests that predicates would FRONT a sentence or proposition, before anything else. So why use 'predicate'?
I know of Latin's flexible word order, but even in Latin, the most common form is ... SOV. So does the prefix prae- jar with the definitions of 'predicate'? I heed the Etymological Fallacy.
there was a mistake when the word was made up
. I just don't understand whether and how and why predicate relates to the definitions.
