dickflüssig

Dickflüssig is a German adjective used to describe a liquid with high viscosity, meaning it flows slowly and has a thick, dense consistency. The word is a combination of dick (thick) and flüssig (liquid). In everyday language it is applied to foods such as honey, syrups, sauces, and molasses, as well as to fluids like certain oils or syrups, where a perceptible thickness is noticeable. The expression is informal and descriptive rather than a precise scientific term.

In science and engineering, viscosity is the property that quantifies how a liquid resists flow. Dynamic viscosity is measured in pascal-second (Pa·s) or millipascal-second (mPa·s); water at room temperature has about 1 mPa·s, while thicker liquids show higher values. Temperature typically reduces viscosity, so a liquid may feel thick at room temperature but become runnier when warmed. Some liquids are non-Newtonian, meaning their viscosity changes with the rate of shear; for example, ketchup is shear-thinning (viscosity decreases under stress), while other suspensions can be shear-thickening.

Dickflüssig is a neutral, descriptive term, often interchangeable with zähflüssig in everyday speech. It conveys a perceptual impression of thickness without implying a specific numeric viscosity. Usage tends toward context-appropriate descriptions of foods, fuels, lubricants, or other liquids where the sense of thickness matters.
