Web$\nabla$: Called Nabla or del. This has four different uses, which can be easily distinguished while reading out loud, but it gets confusing when the first and last uses (grad and covariant derivative) get mixed up with $\partial$ and $\delta$ Gradient/grad: $\vec{\nabla}\phi$ (phi is a scalar). Read as "nabla phi", or "del phi".

The gradient symbol is usually an upside-down delta, and called “del” (this makes a bit of sense – delta indicates change in …
In curvilinear coordinates, or more generally on a curved manifold, the gradient involves Christoffel symbols: ∇ f = g j k ( ∂ f i ∂ x j + Γ i j l f l ) e i ⊗ e k , {\displaystyle \nabla \mathbf {f} =g^{jk}\left({\frac {\partial f^{i}}{\partial x^{j}}}+{\Gamma ^{i}}_{jl}f^{l}\right)\mathbf {e} _{i}\otimes \mathbf {e} _{k},} See more In vector calculus, the gradient of a scalar-valued differentiable function $${\displaystyle f}$$ of several variables is the vector field (or vector-valued function) $${\displaystyle \nabla f}$$ whose value at a point See more The gradient of a function $${\displaystyle f}$$ at point $${\displaystyle a}$$ is usually written as $${\displaystyle \nabla f(a)}$$.
