Etymology: Lustreless is a plain formation: the noun "lustre" with the suffix "-less" attached, meaning "without". The suffix traces back through Old English "-lēas", which was itself a free-standing word meaning "free from" or "devoid of", related to "leas", "loose" or "false". So the word's meaning is built into its parts: a surface that has no lustre. The noun behind it has a longer story. "Lustre" descends from a Proto-Indo-European root that also gave rise to words for light and brightness, and it entered English from Latin "lustrum" through French, where it kept its sense of a shining, reflected brilliance on a surface. The "-less" suffix, meanwhile, is one of the most productive endings in English, which is why it can be stuck onto nearly any noun to describe the absence of that quality.
