(mathematics) The group of all affine transformations of a finite-dimensional vector space.

(geometry, uncountable) The branch of geometry dealing with what can be deduced in Euclidean geometry when the notions of line length and angle size are ignored.

(geometry, linear algebra) A geometric transformation that preserves lines and parallelism, but in general not lengths or angles; (more formally) an automorphism of an affine space: a mapping of an affine space onto itself that preserves both the dimension of any affine subspace and the ratio of the lengths of any pair of parallel line segments.

(chemistry) All the various attractions between elements and compounds that lead to their reaction.

(mathematical analysis, computing) A model for self-validated numerical analysis in which quantities are represented as affine combinations (called affine forms) of certain primitive variables that stand for sources of uncertainty in data or approximations made during computations.

(mathematics) a vector space having no origin

Fraud whose victims are susceptible because they trust the perpetrator as a member of their circle.

(rare) A co-in-law: A relationship by marriage with a separation by three degrees (two people), compared to prototypical affines, where the separation is two and one.
