Burnability

Part of speech: noun

Definitions

1. The characteristic of a substance that describes its likelihood to catch fire and continue to combust under given circumstances

Etymology: "Burnability" is a plain formation: the verb "burn" with the suffix "-ability" attached. That suffix comes from Latin "-abilitas" and entered English through French "-abilité," and it is the same ending found in words like "readability" and "washability." Attaching it to "burn" turns the verb into a noun meaning how easily something catches fire and keeps burning. The pattern is productive because English speakers can generate new "-ability" nouns freely from almost any verb, so "burnability" is a transparent, ready-made term rather than a word with a dramatic backstory. Its meaning follows directly from its parts, with no sense shift from an earlier use.
