Here are some terms and people who deserve definitions.
 0vector
 A scalar.
 1vector
 A vector.
 2vector
 A bivector.
 3vector
 A trivector.
 Bivector

 Blade
 Hestenes' term for a multivector with no scalar part, to emphasise their
directional nature.
 Clifford
 William Kingdon
Clifford. English geometer. 18451879. "If he had lived we
might have known something."
 Complex number

 Conjugation

 Dilation
 To change in magnitude or
scale, as by multiplying by a scalar. Also written as
dilatation.
 Flat
 A linear subspace.
 Floating point
number
 A computer approximation to a real number.
 Geometric product

 Gibbs
 Josiah Willard Gibbs. American
mathematical physicist. 18391903.
 Grade

 Grassmann
 Hermann Grassmann.
German scholar. 18091877.
 Hamilton
 Sir William Rowan
Hamilton. Irish mathematical physicist. 18051865.
 Heavisides
 Oliver Heavisides.
English researcher. 18501925.
 Hestenes
 David Hestenes.
 Imaginary number

 Inner product

 Magnitude
 The value of a scalar, the length of a vector, the area of a bivector, the volume of a trivector, or the sum of all these in
a mixed multivector.
 Multiblade

 Multivector

 Outer product

 Pseudoscalar

 Quaternion

 Real number

 Reflection
 A transformation
which preserves distances and leaves a plane, the plane of
reflection, unchanged.
 Reversion
 Unary operation on a multivector which negates those
components which would change sign if their vector factors
were reversed in order. Hence the reversion of
x is x, but the reversion of xy is
xy.
 Rotation
 A transformation which
preserves distances and leaves a line, the axis of rotation,
unchanged.
 Scalar
 A real
number.
 Translation

 Trivector
 A directed volume.
 Unitary
 Having a magnitude of one.
 Vector
 A directed length.
 Vector cross product

 Vector dot product
