Why this word is great
INBREAK — [Noun/Verb] A sudden, forcible incursion, or the act of making one. From Middle English *inbreken*, from Old English *inbrecan* (“to break into”), equivalent to the prefix *in-* (“into”) + *break*. Unlike “incursion,” a general term for a hostile advance, or “intrusion,” which suggests a furtive or unwelcome encroachment, an *inbreak* is defined by the violent fracturing of a boundary. It is the shriek of glass as a stone flies through the dark, the first brutal crest of a flood through a levee, or the unbidden memory that cracks the sealed vault of composure—a testament that no perimeter, whether of stone or of self, is ultimately permanent.
