- an underground passage.
- a passageway, as for trains or automobiles, through or under an obstruction, as a city, mountain, river, harbor, or the like.
- an approximately horizontal gallery or corridor in a mine.
- the burrow of an animal.
- Dialect. a funnel.
- to construct a passageway through or under: to tunnel a mountain.
- to make or excavate (a tunnel or underground passage): to tunnel a passage under a river.
- to move or proceed by or as if by boring a tunnel: The river tunneled its way through the mountain.
- to pierce or hollow out, as with tunnels.
- to make a tunnel or tunnels: to tunnel through the Alps.
Origin of tunnel
- Physics. a quantum-mechanical process by which a particle can pass through a potential energy barrier that is higher than the energy of the particle: first postulated to explain the escape of alpha particles from atomic nuclei.

- (intr; foll by through, under, etc) to make or force a way (through or under something)he tunnelled through the bracken
- physics the phenomenon in which an object, usually an elementary particle, tunnels through a potential barrier even though it does not have sufficient energy to surmount the barrier. It is explained by wave mechanics and is the cause of alpha decay, field emission, and certain conduction processes in semiconductors
Word Origin and History for tunneling
mid-15c., "funnel-shaped net for catching birds," from Middle French tonnelle "net," or tonel "cask," diminutive of Old French tonne "tun, cask for liquids," possibly from the same source as Old English tunne (see tun).
Sense of "tube, pipe" (1540s) developed in English and led to sense of "underground passage," which is first attested 1765, about five years after the first modern tunnel was built (on the Grand Trunk Canal in England). This sense subsequently has been borrowed into French (1878). The earlier native word for this was mine. Meaning "burrow of an animal" is from 1873. Tunnel vision first recorded 1949. The figurative phrase light at the end of the tunnel is attested from 1922.
"excavate underground," 1795, from tunnel (n.).
- A passage located through or under a barrier.
- See quantum tunneling.
