The opposite of the preposition "to" can vary depending on context, but one common opposite is "from," which indicates a point of origin rather than a direction or destination. For example, while "to" suggests movement towards a place, "from" indicates movement away from it. Another opposite could be "against," especially in contexts involving opposition or contrast.
