noun. A departure from what is typical.

noun. A disorder or abnormal alteration in one's mental state.

noun. undefined

noun. A defect of focus, such as blurring in an image.

noun. An imperfect image caused by a physical defect in an optical element, as in a lens.

noun. The apparent displacement of the position of a celestial body in the direction of motion of an observer on Earth, caused by the motion of Earth and the finite velocity of light.

noun. A deviation in the normal structure or number of chromosomes in an organism.

noun. The act of wandering away; deviation; especially, in a figurative sense, the act of wandering from the right way or course; hence, deviation from truth or moral rectitude.

noun. Vicarious hemorrhage.

noun. Diapedesis of blood-corpuscles.

noun. Congenital malformation.

noun. In zoology and botany, deviation from the type; abnormal structure or development.

noun. In optics, a deviation in the rays of light when unequally refracted by a lens or reflected by a mirror, so that they do not converge and meet in a point or focus, but separate, forming an indistinct image of the object, or an indistinct image with prismatically colored edges.

noun. In astronomy, the apparent displacement of a heavenly body due to the joint effect of the motion of the rays of light proceeding from it and the motion of the earth.

noun. The act of wandering; deviation, especially from truth or moral rectitude, from the natural state, or from a type.

noun. A partial alienation of reason.

noun. A small periodical change of position in the stars and other heavenly bodies, due to the combined effect of the motion of light and the motion of the observer; called annual aberration, when the observer's motion is that of the earth in its orbit, and daily or diurnal aberration, when of the earth on its axis; amounting when greatest, in the former case, to 20.4'', and in the latter, to 0.3''. Planetary aberration is that due to the motion of light and the motion of the planet relative to the earth.

noun. The convergence to different foci, by a lens or mirror, of rays of light emanating from one and the same point, or the deviation of such rays from a single focus; called spherical aberration, when due to the spherical form of the lens or mirror, such form giving different foci for central and marginal rays; and chromatic aberration, when due to different refrangibilities of the colored rays of the spectrum, those of each color having a distinct focus.

noun. The passage of blood or other fluid into parts not appropriate for it.

noun. The producing of an unintended effect by the glancing of an instrument, as when a shot intended for A glances and strikes B.

noun. a disorder in one's mental state

noun. a state or condition markedly different from the norm

noun. an optical phenomenon resulting from the failure of a lens or mirror to produce a good image

""I suspect it's month by month," Greenspan said of continued economic growth, adding that "a statistical aberration is possible.""
