a child who learned to fear deadlines instead of the dark.
means An adult; a fully matured person, especially as seen from a child's point of view.
from A plain compound of "grown" and "up," stacking two old English bones: "grow" traces back to Old English grōwan, kin to "green" and "grass," the vocabulary of things that sprout; "up" is the equally ancient Old English upp. "Grown-up" as a phrase for the finished, fully-sprouted human is centuries old, but its use as a single noun — the cozy nursery word a child uses for the tall people in charge — is largely a 19th-century habit, the language tidying "grown up" into one settled idea.
