interminable
adjective
Did you know?
We promise not to ramble on endlessly about the origins of interminable. This word was borrowed into English in the 15th century, from a Latin word combining the prefix in- ("not") and the verb terminare, meaning "to terminate" or "to limit." Interminable describes not only something without an actual end (or no end in sight, such as "interminable traffic"), but also events, such as tedious lectures, that drag on in such a way that they give no clear indication of ever wrapping up. Some relatives of interminable in English include terminate, determine, terminal, and exterminate.
