This question poses a paradox of meaning. The general question is whether, if two sentences (x and y) can be used in the same situation, with the same literal meaning, and x and y only differ in that x has morphological affixes that y doesn't, aren't the surplus affixes "meaningless" by the alternation test?
Take this example:
I put the chicken inside a preheated oven.
Wouldn't it make more sense to say:
I put the chicken inside a heated oven.
There is only two states an oven can possibly be in—heated or unheated.
Another example: Does first-class board the plane, or pre-board the plane? What does that mean—to get on before you get on?
