In the context of the geometrization philosophy,
a covariant field theory is constructed. The theory satisfies
the unification principle. The field equations of the
theory are constructed depending on a general differential
identity in the geometry used. The Lagrangian scalar
used in the formalism is neither curvature scalar nor torsion
scalar, but an alloy made of both, the W-scalar. The
physical contents of the theory are explored depending on
different methods. The analysis shows that the theory is
capable of dealing with gravity, electromagnetism and material
distribution with possible mutual interactions. The
theory is shown to cover the domain of general relativity
under certain conditions.
