Why MATLAB has a confusing function name such as griddata (or griddatan)?

I am really confused by the function names griddata and griddatan, because these function names are prefixed by grid whereas the functions are actually doing scattered data interpolation, rather than gridded data interpolation.
In contrast, interpolant class names such as griddedInterpolant (gridded data interpolation) and scatteredInterpolant (scattered data interpolation) have no confusion at all, because these names are consistent with their functional behaviors.

griddata is a verb and noun. It puts the data into a grid, which is the verb "grid"
griddedInterpolant is an adjective and a noun.

I understand the name griddata puts some emphasis on the gridded query points, but this function also works for scattered query points. Why there must be some emphasis on the grid aspect? Why not emphasize both aspects or neither?

griddata has existed since R13 or before, and the emphasis was on querying at grids of points. The name probably seemed like a good idea at the time, which was long before the *Interpolant routines.
