Well, I can tell you that a scalar field means that the field only has a field strength value at any given point; as opposed to a vector field which has a field strength value and a direction. Think about a magnetic field and you have some idea of what a vector field is.

I can also tell you that “spin” is a quantum property of particles. It’s like angular momentum but not exactly angular momentum. We don’t really understand what it is so we call it spin because that’s a close enough analogy to let us reason things out about it.

I don’t understand enough about quantum fields in general or the Higgs field in particular to tell you what the significance of it being a spin-0 scalar field would be.

So when I think "field" I imagine a large plane, probably with some sort of grid overlaid. More accurately, I think in my mind the "field" is the grid points themselves.. I can imagine it's n-dimensional as well just fine, of course.

So I just found this definition : "The word ‘field' signifies the variation of a quantity(whether scalar or vector) with position."

I think a spin-0 (spherical symmetry with no preferred axis) field, then, is scalar because if the uniformity of the higgs particles.

I know that's not explaining the significance but did that sound right at all so far?

I don't think that's quite it, although I admit this is at the borders of my understanding of physics. Spin isn't a property of the field, it's a property of the particles generated by the field. It has nothing to do with the field being scalar or not.
