## Definitions

### from The American Heritage® Dictionary of the English Language, 5th Edition.

• noun A curve on a plane that winds around a fixed center point at a continuously increasing or decreasing distance from the point.
• noun A three-dimensional curve that turns around an axis at a constant or continuously varying distance while moving parallel to the axis; a helix.
• noun Something having the form of such a curve.
• noun Printing A spiral binding.
• noun The course or flight path of an object rotating on its longitudinal axis.
• noun A continuously accelerating increase or decrease.
• adjective Of or resembling a spiral.
• adjective Circling around a center at a continuously increasing or decreasing distance.
• adjective Coiling around an axis in a constantly changing series of planes; helical.
• adjective Printing Relating to or having a spiral binding.
• intransitive verb To take a spiral form or course.
• intransitive verb To rise or fall with steady acceleration.
• intransitive verb To cause to take a spiral form or course.

### from The Century Dictionary.

• noun A loop in a railroad line used to overcome steep grades in a mountainous region by carrying the line through a continuously rising curve.
• noun of a point: The origin of coördinates O corresponds to v = o, and the asymptotic points, P′ , P1, round which the curve goes in an ever-closing spiral, correspond to v = ±∞. The intrinsic equation, expressing the relation between the arc σ (measured from O)and the inclination φ of the tangent at any point to the axis of x, is φ = ½πσ.
• To assume a spiral form; move in a spiral course.
• To make spiral; cause to move spirally.
• Of or pertaining to a spire or coil; like a spire; pointed or shaped like a spire.
• Winding around a fixed point or center, and continually receding from it, like a watchspring; specifically, in conchology, making a number of turns about the columella or axis of the shell; whorled.
• Winding and at the same time rising or advancing like a screw-thread: more accurately helical or helicoidal.
• noun In geometry, a plane curve which runs continuously round and round a fixed point, called the center, with constantly increasing radius vector, so that the latter is never normal to the curve; also, a part of such a curve in the course of which the radius from the center describes 360°.
• noun A helix or curve which winds round a cylinder like a screw.
• noun A spiral spring.
• noun In wool, one of the curls or convolutions in wool-fiber, the number of which in a unit of length is made the basis of an estimate of its quality for manufacturing.
• noun In zoology and anatomy, a spiral formation, as of a univalve, of the cochlea, etc.

### from the GNU version of the Collaborative International Dictionary of English.

• noun (Geom.) A plane curve, not reëntrant, described by a point, called the generatrix, moving along a straight line according to a mathematical law, while the line is revolving about a fixed point called the pole. Cf. helix.
• noun Anything which has a spiral form, as a spiral shell.
• noun a plane curve which cuts all its generatrices at the same angle. Same as Logarithmic spiral, under Logarithmic.
• noun a spiral the law of which is that the generatrix moves uniformly along the revolving line, which also moves uniformly.
• adjective Winding or circling round a center or pole and gradually receding from it.
• adjective Winding round a cylinder or imaginary axis, and at the same time rising or advancing forward; winding like the thread of a screw; helical.
• adjective (Geom.) Of or pertaining to a spiral; like a spiral.
• adjective (Mach.) a gear resembling in general a spur gear, but having its teeth cut at an angle with its axis, or so that they form small portions of screws or spirals.
• adjective a kind of gearing sometimes used in light machinery, in which spiral gears, instead of bevel gears, are used to transmit motion between shafts that are not parallel.
• adjective an operculum whih has spiral lines of growth.
• adjective any shell in which the whorls form a spiral or helix.
• adjective See the Note under Spring, n., 4.

• noun geometry A curve that is the locus of a point that rotates about a fixed point while continuously increasing its distance from that point.
• noun informal A helix.
• adjective Helical, like a spiral
• verb intransitive To move along the path of a spiral or helix.
• verb figuratively, intransitive To increase continually.

• noun a structure consisting of something wound in a continuous series of loops
• noun a curve that lies on the surface of a cylinder or cone and cuts the element at a constant angle
• noun a plane curve traced by a point circling about the center but at increasing distances from the center
• noun ornament consisting of a curve on a plane that winds around a center with an increasing distance from the center
• adjective in the shape of a coil
• verb to wind or move in a spiral course

• That of the right eye which we know as the spiral field, becoming more and more contracted as the perimeter test is continued, is what is found in functional cases; that of the left, however, shows a characteristic loss of the lower part of the field of vision, and agrees with the statement of the man that he can see the upper part of my face but not the lower when he looks at me.
