Origin
Hag descends from Old English hægtesse and Proto-Germanic *hagatusjō, literally the creature of the hedge — the boundary between settlement and wilderness — carrying its charge of supernatural female power through fifteen centuries of Germanic linguistic history.
Definition

The Full Story
Proto-Germanicc. 500 BCE – 500 CEwell-attested
The word 'hag' traces to Proto-Germanic *hagatusjō or *hagazusjō, a compound reconstructed from *hagaz (enclosure, hedge, boundary) and *tusjō (spirit, demon), yielding a literal sense of 'hedge-rider' or 'fence-dweller' — a liminal being who straddles the boundary between the domestic and the wild, the living and the dead. The *hagaz element descends from PIE *kagh- (to catch, enclose; wicker fence), cognate with Latin caulae (enclosure) and Welsh cae (fence). The compound concept of the hedge-witch as a boundary-walker is deeply embedded in Germanic religious thought: the hedge (ON: garðr, OE: haga) demarcated the safe infield from the dangerous

The second element of Old English hægtesse — the *-tesse* part — has never been conclusively explained. Some philologists connect it to a root meaning 'demon' or 'spirit'; others see a feminine agent suffix applied to an already lost noun. More striking is the Middle Dutch development: the same stem that gave English 'hag' (witch) gave Dutch 'haghedisse' (hedge-lizard), meaning the Proto-Germanic hedge-compound was so vivid in the popular mind that it got attached to lizards scrambling along boundary
the shift from PIE *kagh- to Germanic *hag-: the PIE velar stop *k shifted to Proto-Germanic *h (first Germanic consonant shift), producing the characteristic h- onset. The semantic journey moves from spatial boundary marker to spirit inhabiting that boundary to malevolent female supernatural agent to mortal woman with supernatural power to pejorative for old woman. This drift from geography to demonology to gender stigma reflects both the Christianisation of Germanic peoples (rebranding indigenous spirit-workers as witches) and the broader misogynist narrowing of female power vocabulary. The shortened form 'hag' enters Middle English by c. 1225, where it glosses Latin lamia and strix, classical synonyms for witch or vampire. Old High German hagazissa and Middle Dutch haghetisse attest the same compound across the West Germanic branch, confirming Proto-Germanic depth for the hedge-spirit concept. Key roots: *kagh- (Proto-Indo-European: "to catch, seize; wicker fence or enclosure; boundary marker"), *hagaz (Proto-Germanic: "hedge, enclosure, boundary between settled and wild space"), *hagatusjō (Proto-Germanic: "hedge-spirit; liminal supernatural female being who crosses the boundary"), hægtesse (Old English: "witch, fury; female supernatural agent of affliction; attested in Anglo-Saxon medical charms").
