Semi-solid

Quasi-solid, false-solid, or partial-solid, or semi-solid are terms for a substance which is not clearly a solid or a liquid. While similar to solids in some respects, such as having the ability to support their own weight and hold their shapes, a quasi-solid also shares some properties of liquids, such as conforming in shape to something applying pressure to it and the ability to flow under pressure. The words quasi-solid, partial-solid, and partial-liquid are used interchangeably. The term "semi-solid" is sometimes used interchangeably with these terms but is not a correct term, as "semi" means two equal halves.
