the.com/conflagration

a fire that outgrew the word fire and demanded a bigger one.

means A large, destructive fire — the kind that consumes buildings, forests, or whole districts, far beyond an ordinary blaze.

from From Latin conflagrare, 'to burn up completely,' built from con- (an intensifying 'thoroughly') plus flagrare, 'to blaze' — the same root that glows beneath flame, flagrant, and even flamingo. So the word carries fire in its bones: flagrare meant to burn brightly, and con- piled on more heat until the burning became total. English borrowed it through Latin, fully aflame, sometime in the 1500s.
