Liquid is a form of matter with a definite volume but no fixed shape. A liquid is made up of tiny vibrating particles of matter, such as atoms and molecules, held together by forces called chemical bonds. Water is, by far, the most common liquid on Earth. Liquid is one of the three classical states of matter (the others being gas and solid). Like a gas, a liquid is able to flow and take the shape of a container. Some liquids resist compression, while others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena.
The density of a liquid is usually close to that of a solid, and much higher than in a gas. Therefore, liquid and solid are both termed condensed matter. On the other hand, as liquids and gases share the ability to flow, they are both called fluids.
Liquid is one of the three primary states of matter, with the others being solid and gas. A liquid is a fluid. Unlike a solid, the molecules in a liquid have a much greater freedom to move. The forces that bind the molecules together in a solid are only temporary in a liquid, allowing a liquid to flow while a solid remains rigid.
The English word spirit (from Latin spiritus "breath") has many differing meanings and connotations, most of them relating to a non-corporeal substance contrasted with the material body. The spirit of a living thing usually refers to or explains its consciousness. The notions of a person's "spirit" and "soul" often also overlap, as both contrast with body and both are understood as surviving the bodily death in religion and occultism, and "spirit" can also have the sense of "ghost", i.e. a manifestation of the spirit of a deceased person.
The term may also refer to any incorporeal or immaterial being, such as demons or deities, in Christianity specifically the Holy Spirit experienced by the disciples at Pentecost.
The English word spirit comes from the Latin spiritus, meaning "breath", but also "spirit, soul, courage, vigor", ultimately from a Proto-Indo-European *(s)peis. It is distinguished from Latin anima, "soul." In Greek, this distinction exists between pneuma (πνευμα), "breath, motile air, spirit," and psykhē (ψυχη), "soul."
