the word that means exactly the same as inflammable, which fooled everyone, so safety won.

means Capable of catching fire and burning easily.

from From Latin 'flammare,' to set on fire (from 'flamma,' flame), plus the '-able' suffix. The older English word was 'inflammable,' built on Latin 'inflammare' (to kindle), where the 'in-' meant 'into,' not 'not.' But people kept reading that 'in-' as a negative — assuming 'inflammable' meant fireproof — so safety authorities in the 20th century pushed 'flammable' as the unambiguous label for things that burn. A rare case of a word being coined to undo a dangerous misunderstanding.
