dielectric definition by Webster's New World
Origin: di(a)- plush electric: so called because it permits the passage of the lines of force of an electrostatic field but does not conduct the current
dielectric definition by American Heritage Dictionary
Origin: di(a)- + electric.

dielectric - Computer Definition
A substance that is not a conductor of direct electric current, a dielectric is an insulator, rather than a conductor. A dielectric permits the passage of the lines of force associated with an electromagnetic field, but does not conduct the current. As dielectrics, however, can sustain an electromagnetic field, they are commonly used in capacitors and between wires in a cable. Dielectrics include rubber, gutta percha, wood pulp, polyethylene, polyvinyl chloride, flouropolymer resin, and Teflon
An insulator (glass, rubber, plastic, etc.). Dielectric materials can be made to hold an electrostatic charge, but current cannot flow through them.
dielectric - Cultural Definition
A material that conducts (see conduction) electricity poorly or not at all. If a voltage is applied to a dielectric, the atoms in the material arrange themselves in such a way as to oppose the flow of electric current (see also current). Glass, wood, and plastic are common dielectrics. (See insulator.)
