- The comet was burning blue in the distance, like a sickly torch, when I first sighted him, but he begun to grow bigger and bigger as I crept up on him. […] Thinks I, it won't do to run into him, so I shunted to one side and tore along. By and by I closed up abreast of his tail.

- Here in England it is, thank God! the custom for us to shunt ourselves off the grand trunk railroad of business, in tearing up and down which our lives are mainly passed, into some quiet siding once every year. […] [W]hen July is running into August, and everything is breaking up, you feel that your business for the season—be it in commerce, law, or literature—is achieved, and that the time for your being temporarily shunted has arrived.

- This important question of the acquisition of Native lands has been treated as a perfect shuttlecock in the hands of the Government. […] So far as we know, it has not even been circulated amongst the Natives, so that it would be a monstrous thing to pass it into law this session. This question will therefore be necessarily shunted—the one question that is admitted to be of supreme importance to the Colony of New Zealand. Then, the question of the Native Land Courts is another of those which have been shunted.

- Routine preoperative shunting of tumor patients is no longer common practice because many patients remain shunt free after tumor removal. Dias and Albright reported a series of 58 patients with posterior fossa tumors and hydrocephalus. Twenty-five patients were shunted preoperatively, 17 had external ventricular drains (EVDs) and 16 had no preoperative ventricular catheterization. Twenty-four of the 33 patients not initially shunted remained shunt free at long-term follow-up.

- (transitive, surgery) To divert the flow of a body fluid.

- 1873, Fleeming Jenkin, “Galvanometers”, in Electricity and Magnetism, New York, N.Y.: D. Appleton and Co. […], §14, page 201:
- The sensibility of a galvanometer may be varied in a very simple manner by the use of what is termed a shunt. A shunt is a resistance coil, or coil of fine wire used to divert some definite portion of a current, taking it past a galvanometer instead of through its coils.
- (firearms) The shifting of the studs on a projectile from the deep to the shallow sides of the grooves in its discharge from a shunt gun.

- In length, this gun was the same as the French, but weighed 9 cwt. less. It was rifled in six grooves on the shunt plan, in the form in which it has been generally applied to large guns, with the difference that some of the angles of the grooving were rounded off. […] To impede fouling, a slightly greater windage was allowed in the chamber of the shunt gun, the diameter there being 0.04 greater than at the mouth of the bore.

- The shunt system, of which the 64-pr. is the only example now in the service, has been considered inferior to the Woolwich, because besides being unnecessarily complicated, the grooves which are cut with abrupt sharp angles weaken the gun. […] [I]n the shunt gun, however, in addition to the mere fact of the driving side of the double groove being shallow, and the loading side deep, the two grooves join in one deep one at 2 feet 7.5 inches from the muzzle, […]
- (medicine, veterinary medicine) An abnormal passage between body channels.

- Portosystemic shunts can be congenital or acquired with congenital PSS commonly comprising a single communicating vessel between the portal venous circulation and the systemic circulation via the caudal vena cava or azygos vein. Of congenital shunts, 66–75% are extrahepatic. Intrahepatic portosystemic shunts are most commonly identified in larger breeds of dog (though we have also seen a number of terriers with intrahepatic shunts through our clinic).
- (surgery) A passage between body channels constructed surgically as a bypass; a tube inserted into the body to create such a passage.

Newton, […], published 1840, OCLC 1029229898, page 74:
- These improvements consist, firstly, in a novel construction of apparatus to be attached to or applied upon railways, at those parts termed switches, shunts, or moveable rails, which are commonly used for transferring engines, carriages, or trains, from one line of rails to another, as occasion may require, and which apparatus I call a "switch or shunt protector."

- At the first race in Brazil, I became involved in a four-car shunt. I won't go into too much detail now, except to say that the accident had nothing to do with me. […] Everyone else was avoiding the accident when [Jos] Verstappen lost control on the grass, came right into me – and off we all went. It was a huge shunt.
