What does extinguishable mean?
"Extinguishable" is an adjective meaning capable of being put out, quenched, or brought to an end. It applies most literally to fires and flames that can be doused or suppressed, but it can also describe more abstract things — hopes, passions, rights, or disputes — that are capable of being terminated. The word derives from Latin "exstinguere" (to quench), via Old French "extinguiss-", and entered English in the early modern period alongside related forms like "extinguish" and "extinction." In practice, "extinguishable" is considerably rarer than its negative counterpart "inextinguishable," which describes flames or passions that refuse to die. Writers tend to reach for the positive form in technical, legal, or insurance contexts — for example, when specifying whether a particular type of fire can be safely controlled with standard equipment — rather than in everyday conversation, where simpler phrasings such as "can be put out" usually suffice.

It's the rare opposite of inextinguishable — a word you'll almost only ever meet as someone else's negation.

Etymology of extinguishable
"Extinguishable" comes from the Latin verb "exstinguere," meaning to quench or destroy (literally to prick out or stamp out), formed from "ex-" (out) and "stinguere" (to prick or quench). It passed into English through Anglo-Norman and Old French "extinct-/extinguiss-," first appearing in English texts in the 16th century. It shares this Latin root with "extinction," "distinct," and even "instinct," all of which descend from the same ancient stem relating to pricking or quenching.
How extinguishable is actually used
Relatively formal and technical in register; far more common in its negative form 'inextinguishable'. Often found in safety, insurance, and legal contexts when describing fires or liabilities.
Easily confused with extinguishable
Inextinguishable means the opposite — impossible to put out or end — while extinguishable simply means capable of being put out or ended.
