## AI Etymology
Unbreakable is from un- ('not') + breakable. Break descends from Old English brecan ('to break, shatter'), from Proto-Germanic *brekan, from Proto-Indo-European *bhreg- ('to break'). Important recorded forms include un- (Old English), brecan (Old English), and *bhreg- (Proto-Indo-European). Morphologically, the un- element marks negation, reversal, removal, or deprivation, while the base supplies the action, quality, or state being denied or undone. The modern sense continues the older lexical line without requiring a separate origin. In current use it covers impossible to break or destroy.
