  While general relativity provides a complete geometric theory of gravity, it
fails to explain the other three forces of nature, i.e., electromagnetism and
weak and strong interactions. We require the quantum field theory (QFT) to
explain them. Therefore, in this article, we try to geometrize the spinor
fields. We define a parametric coordinate system in the tangent space of a null
manifold and show that these parametric coordinates behave as spinors. By
introducing a complex internal hyperspace on a tangent space of a null
manifold, we show that we can get eight sets of such parametric coordinate
systems that can behave as eight spinor fields. These spinor fields contain two
triplets that can rotate among themselves under SU(3). Seven of these spinor
fields also couple with a U(1) field with different strengths. We also show
that while these spinors can be assigned a tensor weight $1/2$ or $-1/2$, in a
$L^p$ space where the coordinates, instead of adding up in quadrature, add up
in $p$th power, we can get a parametric space that contains similar spinors of
tensor weight $1/p$.
