Why do “flammable” and “inflammable” mean the same thing, or is there a difference?

Edit: SERIOUSLY, THANK YOU—

BTW my confusions stems from them having the same meaning online

Flammable: “easily set on fire”
Inflammable: “easily set on fire”

Hmm, maybe people are too young to remember this!

 

Initially when I lived in the USA in the 1950’s, combustible materials were required to have a label stating “INFLAMMABLE” meaning they can inflame.

However, this confused some workers, who didn’t know the meaning of ‘inflammable’ and guessed from the prefix that it meant non-flammable.

 

The clever solution was to actually *coin a new word that had never existed before* which was the word ‘flammable.’

 

Virtually anyone seeing a warning ‘flammable’ knew that the substance being carried was inflammable. Grammar perfectionists would be *annoyed* but accidents were prevented.
