Etymology: "Rattlebrained" is a plain compound: "rattle" joined to "brained," with "brained" built from "brain" plus the suffix "-ed," meaning "having a brain of a particular kind." The picture is of a head with brains that rattle around loosely, like pebbles in a tin, so the thoughts inside have no fixed order. "Rattle" in this sense draws on its older meaning of noisy, rapid motion or talk, the same sense behind "rattle off" a list. Combined with "brained," it describes a mind that seems to shake and clatter rather than settle into a steady line of reasoning. The compound is transparent enough that its meaning was clear from its parts, which is why it has stayed a straightforward, descriptive insult rather than a term with a dramatic backstory.
