What do you call the origin of a vector? I don't think that's a notion in vector spaces.

Vector spaces have an addition identity normally referred to as the 0 vector.

When drawing vectors, such as on a 2D space, the origin is identified with this 0 vector, and then the points in the 2D space can be associated with the vectors in the vector space.
