What's an intuitive derivation or rationale to help remember the definition? I purpose to burrow below definitions, which I already understand so ask NOT about. I heed the Etymological Fallacy.
decree = {noun} 1. An official
order
that has the force of law:= {verb} [with object] Order (something) by decree
Etymonline: early 14c., from Old French decre, variant of decret (12c., Modern French décret), from Latin decretum, neuter of decretus, past participle of decernere "to decree, decide, pronounce a decision," from de- (see de-) + cernere "to separate" (see crisis).
My especial concern:
How does "to separate" effect/imply/induce the definitions, given that "to separate" (the original) and order
(modern) fail to relate to each other?
Footnote: Unhelpfully and oddly, OED's entries for the verb and the noun are both too terse.
