Stuðlar

Stuðlar is the plural form of stuðull, an Icelandic word with several related meanings. In mathematics and statistics, stuðull refers to a coefficient: a number that multiplies a variable in an algebraic term or that weights a term in a model. For example, in a linear model such as y = a + b x, the value b is a stuðull in relation to x. The term is widely used to describe the factors that determine or scale outcomes in equations, polynomials, and statistical analyses.

In structural and architectural language, stuðlar can also mean supports, props, or pillars that bear loads or stabilize a construction. A beam may be held up by several sturdy stuðlar, especially in descriptions of buildings or frameworks.

The verb stuðla means to support or promote, and the noun form underpins both physical and figurative senses of backing or assisting. Thus, one can speak of supporting a project, policy, or argument as stuðla to it.

Etymology and usage: stuðull derives from the Icelandic verb stuðla, reflecting the core idea of support or buttressing. The term is common in Icelandic mathematical, scientific, and engineering texts as well as in everyday language when describing factors, weights, or structural supports.
