Etymology: Nucleoplasm is a compound built from two Greek-derived parts. Its first element, "nucleo-", comes from Latin "nucleus", meaning "kernel" or "core", a diminutive of "nux", "nut". The Latin word traces back to a Proto-Italic root, "knuks", which shares its ancestry with the ordinary English word "nut" and so, in a sense, the word for the central part of a cell is a relative of the hazelnut. The second element, "plasm", comes from Greek "plasma", meaning something moulded or formed, from the verb "plassein", to shape or mould. English took "plasm" as a combining form, so that words like "protoplasm" and "nucleoplasm" describe living substance as something shaped. Nucleoplasm is therefore literally "the stuff of the kernel": the fluid that fills the nucleus of a cell, surrounding the chromosomes and nucleoli. The word is a modern scientific coinage built from classical parts, not a term used by the ancient Greeks or Romans.
