Etymology: "Nanorod" is a plain compound: "nano-" joined to "rod." The prefix comes from the Ancient Greek "nânos," meaning "dwarf," which passed into Latin as "nānus" and later into English as a combining element. In modern science "nano-" means one billionth (10⁻⁹) of a unit, so a nanorod is a rod-shaped particle measuring only billionths of a metre across. The second half is much older. "Rod" descends from the Old English "rodd," a word for a stick or pole, and it has kept that plain physical sense for centuries. Joining the two gives a name that is literally a "dwarf rod," with the prefix describing scale rather than shape.

Synonyms: nanoparticle rod, nanowire
