super-, supra-, sur- +

1. To charge with an abundant or excessive amount, as of energy, emotion, or tension.
2. To force air into an internal-combustion engine at a pressure significantly above the atmospheric pressure at the start of the compression stroke; the degree of pressure retained determines the level of supercharging.

1. Equipped with a supercharger.
2. A reference to gas or liquid; subjected to pressurization.
3. Full of energy, emotion, tension, etc.

1. A mechanism for forcing air into an internal-combustion engine in order to increase engine power.
2. A blower or compressor, usually driven by the engine, for supplying air under high pressure to the cylinders of an internal-combustion engine.

1. Of or pertaining to anything above the eyebrow.
2. Having a conspicuous line or marking over the eye, as certain birds.
3. Situated on the frontal bone at the level of the eyebrow.

1. Expressive of contempt: "He curled his lip in a supercilious smile."
2. Having or showing arrogant superiority to and disdain of those someone views as unworthy: "Her mother eyed my clothes with a supercilious attitude."
3. Disdainful or contemptuous; full of or characterized by pride or scorn.
4. Anyone who arches his/her eyebrows and looks down her/his nose at someone; in other words, "a high brow".
5. Etymology: from Latin with special reference to a facial expression with raised eyebrows; hence, pride, haughtiness; from super, "above" + cilium, "eyelid".

When someone raises his/her eyebrows, it doesn't necessarily mean she/he is disdainful, contemptuous, etc. Such action may also express surprise, curiosity, etc. Consider the context, or particular situation, before accusing someone of being supercilious.

With a sneer; in an uncomplimentary sneering manner.

The trait of displaying arrogance by patronizing those considered inferior.

1. The eyebrow, or the region of the eyebrows.
2. An individual hair of the eyebrow.
3. The arch of hair above each eye; eyebrow, brow.

An association of clusters of galaxies.

Superclusters are large assemblages of smaller galaxy groups and clusters, and are among the largest structures of the cosmos.

The existence of superclusters indicates that the galaxies in our Universe are not uniformly distributed; most of them are grouped together in groups and clusters, with groups containing up to fifty galaxies and clusters up to several thousand.

Those groups and clusters and additional isolated galaxies in turn form even larger structures called "superclusters".

A term for any extremely powerful, large-capacity computer, that is capable of processing huge amounts of data in an extremely short time.

A technology in which the superconducting characteristics of low-temperature materials produce intense magnetic fields to store energy; proposed as a storage option in photovoltaics to smooth out fluctuations in power generation.

A massive ring particle accelerator that was planned to be built by the U.S. government near Waxahachie, Texas.

Due to concern over the high cost of the project, it was eventually canceled by Congress in 1993 after 22.5 kilometers (14 miles) of its tunnel had already been excavated and $2 billion was spent (wasted).

A phenomenon shown by certain metals, alloys, and other compounds of having negligible resistance to the flow of electric current at temperatures approaching absolute zero.

Certain materials are now known to exhibit superconductivity at temperatures well above absolute zero.

1. Highly critical or judgmental.
2. Of, pertaining to, or designating a fluid at a temperature and pressure greater than its critical temperature and pressure.

Water normally boils as temperature rises, but if both pressure and temperature push up beyond a certain critical point, the gas and liquid phases merge into a supercritical fluid that is denser than steam but lighter than liquid water

Supercritical water is especially effective at leaching metals and other nutrients out of rock. Some, such as sulphur, provide energy for the organisms that live around vents, which have no light to start a food chain; also iron is essential for the growth of plankton.

1. In Freudian theory, the division of the unconscious that is formed through the internalization of moral standards of parents and society, and that censors and restrains the ego.
2. In psychoanalytic theory, the division of the psyche that censors and restrains the ego and has identified itself unconsciously with important people from early life. It results from incorporating the values and wishes of these people into one's own standards.
