Etymology
The word 'wormhole' is a Modern English compound formed from two ancient Germanic roots. The first element, 'worm', descends from Proto-Germanic wurmiz, itself from Proto-Indo-European wr̥mis, meaning 'worm, serpent', reflecting the creature's sinuous, burrowing nature. The second element, 'hole', originates from Proto-Germanic hulą, from pie kel-, meaning 'to cover, conceal', which evolved to denote a hollow, concealed space. The literal sense, a hole made by a worm, has been in use for centuries. Its application in theoretical physics, coined in the 20th century, is a metaphorical extension, visualizing a hypothetical tunnel through the fabric of spacetime as resembling the burrow of a worm through an apple, connecting two distant points via a shortcut.
