Rrotullimit

Rrotullimit is a term used in Albanian to denote the process or state of turning around an axis, commonly translated into English as rotation or turning. The word is formed from the root rrotull- (to turn around) plus the suffix -im, which marks abstract nouns or processes. The definite form is rrotullimi, while rrotullimit appears in contexts requiring a determinate or possessive construction, such as in phrases that specify “of the rotation.”

In everyday language, rrotullimit refers to any turning motion around an axis, for example a wheel spinning, a page rotating on a hinge, or a device that spins. In scientific and technical contexts, rrotullimi is used to describe the mathematical and physical concept of rotation: a rigid motion that preserves distances and angles. In mathematics, rotations are described as transformations that, in two or three dimensions, can be represented by rotation matrices and, in three dimensions, belong to the group SO(2) or SO(3), preserving the inner product and orientation.

Etymology and forms: the term derives from the Albanian verb stem rrotull-, meaning to revolve or turn, with the noun-forming suffix -im. The language distinguishes rrotullimin (the rotation, definite) from rrotullimit (genitive or other determinate forms) depending on context.
