Thermobaric

/ˌθɜːrmoʊˈbærɪk/adjective

Describing a weapon that scatters fuel as an aerosol and ignites it, killing by sustained heat and blast pressure.

The Greek roots

θερμός
thermós
hot, warm
+
βάρος
báros
weight, pressure

Literally: heat and pressure

The story of the word

Two plain Greek nouns, heat and weight, name a weapon that works by pressure rather than fragments. Because the fuel burns using oxygen from the surrounding air, the blast wave lasts longer than a packed charge and reaches around corners into caves and rooms. Militaries also call these fuel-air explosives, which is more honest about the mechanism than the Greek is.
