Outfoxed can be defined as being tricked or outsmarted by someone or something. The antonyms for this word, then, would be to trick or outsmart someone or something, using words such as outwit, outmaneuver, thwart, or surpass. To outwit someone is to use your intelligence and cunning to defeat or overcome them, while outmaneuver means to gain an advantage by maneuvering around them. Thwart, on the other hand, means to prevent someone from achieving their goal, and to surpass means to exceed or be better than them. These antonyms are all about gaining a strategic advantage over someone or something, rather than being the one who is outsmarted.
