jordanian-palestinian

The term is a modern political and cultural compound, created by linking two established demonyms with a hyphen. 'Jordanian' originates from the name of the Jordan River (Hebrew 'Yarden', meaning "descender"), which gave its name to the Hashemite Kingdom of Jordan. 'Palestinian' derives from 'Philistine', the name of an ancient people of the region, via Latin 'Palaestina', the Roman province name. The hyphenated form 'Jordanian-Palestinian' emerged in the latter half of the 20th century to describe matters of joint concern, relations, or shared identity between the two entities, reflecting the intertwined history and politics of the Levant.

This is a hyphenated compound adjective formed from two demonyms: 'Jordanian' (from Jordan, the country name + the suffix -ian) and 'Palestinian' (from Palestine, the region name + the suffix -ian). Each component is a proper adjective derived from a geographic name.
