1 (physical chemistry) a distinct state of matter in a system; matter that is identical in chemical composition and physical state and separated from other material by the phase boundary; "the reaction occurs in the liquid phase of the system" [syn: form]
2 any distinct time period in a sequence of events; "we are in a transitional stage in which many former ideas must be revised or rejected" [syn: stage]
3 a particular point in the time of a cycle; measured from some arbitrary zero and expressed as an angle [syn: phase angle]
4 (astronomy) the particular appearance of a body's state of illumination (especially one of the recurring shapes of the part of Earth's moon that is illuminated by the sun); "the full phase of the moon"
1 arrange in phases or stages; "phase a withdrawal"
2 adjust so as to be in a synchronized condition; "he phased the intake with the output of the machine"
- That which is exhibited to the eye; the appearance which anything manifests, especially any one among different and varying appearances of the same object.
- Any appearance or aspect of an object of mental
apprehension or view
- The problem has many phases.
- A particular appearance or state in a regularly recurring cycle of changes with respect to quantity of illumination or form, or the absence, of its enlightened disk; as, the phases of the moon or planets. Illustrated in Wikipedia's article Lunar phase.
- Any one point or portion in a recurring series of changes, as in the changes of motion of one of the particles constituting a wave or vibration; one portion of a series of such changes, in distinction from a contrasted portion, as the portion on one side of a position of equilibrium, in contrast with that on the opposite side.
- (to phase out) To discontinue (doing) something over a period of time (i.e., in phases).
- To stun or shock someone.
- To become stunned or shocked.
Usage notesThe sense of phase meaning stunned or shocked is a misspelling of the intended word faze. This has become fairly common nonstandard use. See notes at faze.
A phase is one point or portion in a recurring series of changes. Phase or phases may also refer to:

- The current (time varying) state of a cyclic phenomenon
