ETYM Latin accommodatio, from accommodare: cf. French accommodation.
1. (Physiology) The automatic adjustment in focal length of the lens of the eye.

3. In the theories of Jean Piaget: the modification of internal representations in order to accommodate a changing knowledge of reality.
4. Living quarters provided for public convenience.

Adjustment, especially of eye muscles; adaptation; lodgings; loan. accommodation bill, bill of exchange co-signed by a guarantor. accommodation train, American, train stopping at all or most stations.
In biology, the ability of the eye to focus on near or far objects by changing the shape of the lens.
For an object to be viewed clearly its image must be precisely focused on the retina, the light-sensitive layer of cells at the rear of the eye. Close objects can be seen when the lens takes up a more spherical shape, far objects when the lens is flattened. These changes in shape are caused by the movement of ligaments attached to a ring of ciliary muscles lying beneath the iris.
From about the age of 40, the lens in the human eye becomes less flexible, causing the defect of vision known as presbyopia or lack of accommodation. People with this defect need different glasses for reading and distance vision.
ETYM Cf. French adaptation, Late Lat. adaptatio.
In biology, any change in the structure or function of an organism that allows it to survive and reproduce more effectively in its environment. In evolution, adaptation is thought to occur as a result of random variation in the genetic makeup of organisms coupled with natural selection. Species become extinct when they are no longer adapted to their environment—for instance, if the climate suddenly becomes colder.
This produces individuals whose genetically determined characteristics allow them to survive and reproduce more effectively. Thus, the webbed feet of ducks or otters are adaptations to living in water, enabling them to swim more efficiently. In physiology, adaptation is said to occur in sense organs, when the sensitivity of an organ alters in response to changes in environmental conditions. Examples include an increase in the size of the eye's pupil to admit more light as night falls.
1. The process of adapting to something (such as environmental conditions); SYN. adjustment.
2. (Physiology) The responsive adjustment of a sense organ (as the eye) to varying conditions (as of light).
3. A written work (as a novel) that has been recast in a new form; SYN. version.
ETYM Cf. French ajustement. Related to Adjust.
1. Making or becoming suitable; adjusting to circumstances; SYN. accommodation, fitting.
2. The act of adjusting something to match a standard; SYN. registration, readjustment.
3. The act of adjusting something to match a standard
4. The process of adapting to something (such as environmental conditions)
5. An amount added or deducted on the basis of qualifying circumstances
ETYM French alignement.
1. The act of adjusting or aligning the parts of a device in relation to each other.
2. The spatial property possessed by an arrangement or position of things in a straight line or in parallel lines.
3. An organization of people (or countries) involved in a pact or treaty
Joining or fitting together.
1. The act of conforming or producing conformity; adaptation
2. Formation of something by appropriate arrangement of parts or elements; an assembling into a whole

1. A small and often standardized accessory to a larger system.
2. Trying on clothes to see whether they fit; SYN. try-on, trying on.
Calibrating something (a musical instrument or electronic circuit) to a standard frequency.
In music, the adjusting of pitch in instruments to the correct intonation, in order to avoid dissonance. For example, orchestral instruments tune to concert pitch (A4). Keyboard instruments are more difficult to adjust, often requiring a professional tuner.
