- n. In geometry, a tore or anchor-ring. See tore, 2.
- n. In architecture, a large convex molding of semicircular profile or a profile of kindred curve, used especially in bases, generally as the lowest member of the base, above the plinth when this is present. It differs from the astragal only in size, the astragal being much smaller. Sometimes called tore. See also cuts under base and column.
- n. In botany, the receptacle of a flower; the more or less enlarged extremity of a stem or floral axis upon which the floral organs are situated. See receptacle, 2 , and cut under myrtle.
- n. In anatomy, a smooth rounded ridge or elongated protuberance, as of a muscle; specifically, the tuber cinereum of the brain, or that part of the floor of the third ventricle which is prolonged downward to form a contracted passage from the cavity of the third ventricle into that of the pituitary body.
- n. In zoology, some part or organ likened to a torus; specially, a ventral parapodium of some annelids.
- n. topology A topological space which is a product of two circles.
- n. mathematics The standard representation of such a space in 3-dimensional Euclidean space: a shape consisting of a ring with a circular cross-section: the shape of an inner tube or hollow doughnut.
- n. topology, in combination, etc. The product of the specified number of circles.
- n. architecture A molding which projects at the base of a column and above the plinth.
- n. botany The end of the peduncle or flower stalk to which the floral parts (or in the Asteraceae, the florets of a flower head) are attached; see receptacle.

“The only moulding known is the clustered torus (_torus_ = a convex moulding of semicircular profile), which resembles a bundle of reeds tied together with cords or ribbons.”
“As a practical matter, to make the ship Climb, or go null, Engineering pumps massive energies into the Climber's torus, which is a closed hyper drive.”
“I say 'of its stalk,' -- that is to say, of the part of the stalk immediately sustaining the seed, commonly called the torus, and expanding into the calyx.”
“The shape of this region is not strictly a torus, since it's considerably flattened, especially at higher distances from the center, but it's referred to as a torus for simplicity.”
“Massimo Piattelli-Palmarini: Very interesting, though his idea that the torus is the mother of all forms is not persuasive.”
“And provided above can connect to below, and left to right, we can wire up a list of lists of processes (i.e. a 2D grid in waiting) into a torus, that is a grid where the top edge connects to the bottom edge and the left edge to the right edge (as is often the case in old arcade games): wrappedGrid:: (Connectable above below, Connectable left right) = >”
“Recall that a torus is the shape of an inner tube, or the surface of a donut: it is a two-dimensional surface with one whole.”
“On a whim, I substituted rotations for translations, and after adding a few floors, generated this bent tower that wraps around on itself to form a torus.”
“For example, what was once dictated as "fracture of forearm," was appropriately elaborated on to become "torus fracture of lower end of right radius," and would be coded "S52.521" based on ICD standards.”
“While there are some good ideas presented here -- like the exploration of gender issues, the idea that prisoners may be 'digitized', and the (perhaps imagined) ill effects of the torus-shaped power source of their transport -- there was too-little actual plot to get a decent handle on this story.”
