Mid 19th century: from French protéine, German Protein, from Greek prōteios 'primary', from prōtos 'first'.
first from Old English:
The Old English word first goes back to an ancient root which is shared by Latin primus (as in prime), and Greek prōtos (as in protein (mid 19th century) and prototype (mid 16th century)). The expression first come, first served goes back to the Middle Ages and is found in the poetry of Geoffrey Chaucer. It was originally used in the context of milling, when a mill would serve the whole community. The first person to bring their corn to the mill would be the first person to have it ground. The first among equals is the member of a group that has the highest status. It is a translation of the Latin phrase primus inter pares, which was used as a title by Roman emperors. Many will know it today as the title of a Jeffrey Archer novel published in 1984. In Scotland to first-foot (early 19th century) is to be the first person to cross the threshold of a house in the New Year. Traditionally, it is thought lucky for that person to be a dark-haired man.
