{a, b, c}, {d, e, f}, {g, h, i} would not be a valid Mathematica expression, it needs some sort of Head (container). What you probably mean is something like,
Apply[f,{{a, b, c}, {d, e, f}, {g, h, i}}] or equivalently
f@@ {{a, b, c}, {d, e, f}, {g, h, i}} where f is some function name.

The Apply replaces the top level List head with another Head of your choice.
