Auto-antonym. In English, "inflammable" is an auto-antonym which can mean either "combustible" or "noncombustible"[1] so English safety labels typically use "Flammable".
In Spanish and French "inflam[m]able" only means "combustible", so a multilingual safety cabinet can appear to be contradictory- is this a cabinet for combustible or noncombustible materials? An auto-antonym (sometimes spelled autantonym), or contronym (also spelled contranym), is a word with a homograph (another word of the same spelling) that is also an antonym (a word with the opposite meaning). Variant names include antagonym, Janus word (after the Roman god), enantiodrome, self-antonym, antilogy, addad (Arabic, singular didd).[2][3] It is a word with multiple meanings, one of which is defined as the reverse of one of its other meanings. This phenomenon is also called enantiosemy,[4] enantionymy or antilogy. Origins[edit] Extra Credits – Gamifying Education.
