chrono-, chron- +

A timepiece so constructed as to exaggerate the effect of changes of temperature upon its rate and used to indicate mean temperature.

Affecting the rate of rhythmic movements; such as, the rate of contractions of the heart.

1. Modification of the rate of a periodic movement, e.g., the heartbeat, through some external influence.
2. Interference with the regularity of periodic movement; such as, the heart beat. 3. An orientation response due to age; used particularly with reference to the movement of leaves in plants.

The science of arranging events in the order of time by the comparative study of the annual growth rings in (ancient) timber.

The opposite or reverse of synchronize.

Lack of synchrony, as in brain waves.

1. Lasting through time, or during the existing period.
2. In medicine, systematically observed over time in the same subjects throughout as opposed to synchronic or cross-sectional; the inferences are equivalent only where there is strict stability of all elements.
3. Pertaining to or designating a method of linguistic study concerned with the historical development of a language; historical, as opposed to descriptive or synchronic.

1. The existence of a geological feature that transgresses palaeontological zones; for example, there is a great divergence between the lithological and chronological classification.
2. In botany, having two periods of growth in the year.

A disturbance in the consciousness of time.

Not agreeing as to time; separate as to time.

Excessive continuous gastric secretion.

1. The chronology of the earth; the measurement of geological time and the ordering of past geological events.
2. The time sequence of the earth’s history as governed by geological events.
3. The science of dating and the study of time in relation to the earth's history as revealed by geological data.

1. An extension of geometry conceived as taking time into account as the fourth dimension; the geometry of space-time.
2. Absolute geochronology, in which events are assigned (approximate) dates in relation to the present instead of to other events.
3. Measurement of geologic time, as through isotopic-radioactive decay.

Any equatorial satellite with an orbital velocity equal to the rotational velocity of the earth resulting in a satellite that is apparently motionless for any observer on the earth.

A geosynchronous satellite has an orbit similar to a geostationary one, except that it does not necessarily lie in the earth's equatorial plane.

1. The application of statistics to vocabulary to determine the degree of relationship between two or more languages and the time of their splitting off from a common ancestor.
2. The determination of how long ago different languages evolved from a common source language.

The branch of lexicostatistics that studies the rate of the replacement of vocabulary and attempts to determine what percentage of basic vocabulary two presently distinct, but related languages share, using the information that is obtained to estimate how long ago they ceased being a single language.
