neliöidä

Neliöidä is a Finnish verb meaning to square, i.e., to raise a number or an algebraic expression to the power of two. The form is derived from the noun neliö (square) with the productive suffix -idä that creates verbs indicating an act or process.

In mathematical usage, neliöidä denotes the operation of squaring. For a real number x, applying neliöidä yields x^2. The square of a real number is always nonnegative. The term appears in educational texts, problem sets, and technical writing, and it is commonly used in contexts such as calculating the square of a value or describing a squaring function in programming or calculators.

Examples in natural language include phrases like “neliöidä luku 5,” which means to square the number 5, yielding 25. In Finnish mathematical notation, the result is often expressed as “5:n neliö on 25” or simply “5:n neliö on 25.” The verb is also used with variables and expressions, for instance “neliöidä x” to indicate the operation on x.

Related terms include neliö (square), neliöinti (the act or process of squaring), neliöjuuri (square root), and the broader concept of potenssi (power). Etymologically, neliöidä is formed from neliö plus the verb-ending suffix -idä, signaling an action performed on a square or into a square.
