international (adj.) Look up international at Dictionary.com
1780, coined by Jeremy Bentham from inter- "between" + national (adj.). In the phrase international jurisprudence. He footnotes the word with:
The word international, it must be acknowledged, is a new one; though, it is hoped, sufficiently analogous and intelligible. It is calculated to express, in a more significant way, the branch of law which goes commonly under the name of the law of nations: an appellation so uncharacteristic, that, were it not for the force of custom, it would seem rather to refer to internal jurisprudence. [Bentham, "Introduction to the Principles of Morals and Legislation"]
As a noun and with a capital -i-, it is short for International Working Men's Association, a socialistic worker's movement with global aims, the first chapter of which was founded in London by Marx in 1864.

1660s, "deadly, destructive," from Latin internecinus "very deadly, murderous, destructive," from internecare "kill or destroy," from inter (see inter-) + necare "kill" (see noxious).

The Latin prefix is said to have had here only an intensive sense; "the Latin word meant merely of or to extermination ... without implying that of both parties" [Fowler].
