Etymon #3
Built for armies
The word descends from Old English, the language of the Anglo-Saxon Chronicle, and was already in use before the Norman Conquest. Its earliest sense involved shelter and lodging: the kind of place a traveller might be taken in for the night. The older meaning behind the modern shelter sense carried something more specific.
Before the modern spelling settled, the word travelled through Middle English in several variant forms, used by writers across the late medieval period. Chaucer reached for it in the General Prologue to the Canterbury Tales, describing the company gathered at the Tabard Inn in Southwark before setting out on the pilgrimage road. The word's earlier life lay in the Old English spoken in the centuries before.
The Old English word was a compound, built from two older roots. The first meant army, a body of soldiers on campaign. The second meant protection, the shelter that kept them safe. Put the two together and the literal meaning emerges: a shelter for an army.
The two roots that built the compound survive separately in modern English. HARRY, in its older sense, means to attack or raid: the same Old English root that meant army, the body of soldiers on the march. BOROUGH preserves the second root, the fortified town built to keep danger out. Both roots survive in English, each preserving one half of the older meaning.
