A unit of speech that is ranked as an uninflected word but expresses some kind of syntactical relationship or some general aspect of meaning. Some grammarians classify all conjunctions, prepositions, and negatives as particles.
an element which occurs in a single form (like a preposition in English) and with a function that does not easily fit into standard parts of speech classifications. Particles very often occur in constructions with certain verbs in English with varying degrees of idiosyncratic interpretation: John took off at great speed (i.e. left). May gave herself up (i.e. surrendered)
a unit of speech expressing some general aspect of meaning or some connective or limiting relation. It can be an article preposition or conjunction, or possibly an interjection or adverb. Particles are not dangerous unless they have been accelerated.
A word like across, away, down, for, in, off, out, up, with combined with a verb to form idiomatic usages in which the combination has the force of a single-word verb: The authorities refused to put up with him.
A tiny mass of material. Airborne particles, material that exist in the atmosphere as a solid or liquid, can be natural, caused by stirring of soil dusts, or anthropogenic. They vary in size from coarse (diameter 3 µm) to fine ( 3µm) . Sometimes inhalable or respirable is used to describe those particles ( 2 µm) which can be inhaled through the nose and enter the lungs.
An aggregation of sufficiently many atoms or molecules that it can be assigned macroscopic properties such as volume, density, pressure, and temperature. But sometimes by particle, without qualification, is meant a subatomic particle such as the proton or neutron (which themselves are composed of other "elementary particles") or the electron. See also particles.
A small discrete object, often having a density approaching the intrinsic density of the bulk material; it may be chemically homogeneous or contain a variety of chemical species; it may consist of solid or liquid materials or both.1
Any discrete unit of material structure; a discernible mass having an observable length, width, thickness, size and shape. By size, the particles range: subatomic or fundamental (protons, neutrons, electrons, etc.); molecular (atoms and molecules, from angstroms to 0.5 µm); colloidal; microscopic (can be resolved by optical microscope, e.g., bacteria); macroscopic (can be resolved by the naked eye).
is used here as a synonym for electrons, atoms and/ or electron-deficient atoms (ions) which are in motion, such as in an electric discharge, or in a flowing gas or plasma. So viewed, cosmic rays and stellar/ solar wind ions are particles.
A relatively small subdivision of matter ranging in diameter from a few angstroms (as with gas molecules) to a few millimeters (as with large raindrops). A particle can have various shapes and dimensions.
In marine and freshwater ecology, a particle is a small object. Particles can remain in suspension in the ocean or freshwater, however they eventually settle (rate determined by Stokes' law) and accumulate as sediment. Some can enter the atmosphere through wave action where they can act as cloud condensation nuclei (CCN).
Particle is a jam band formed in Los Angeles in 2000. The original members were Dave Simmons (guitar), Steve Molitz (keyboard), Eric Gould (bass), and Darren Pujalet (drums). Simmons died shortly after the formation of the band due to a sudden illness.
In dynamics, a point displayed as a dot, streak, sphere, blobby surface, or other effect. You can animate the display and movement of particles with various techniques (for example, keys, expressions, and fields such as gravity).
