- metaphor, simile
- Both are figures of speech in which two things are compared. A simile likens one thing to another, dissimilar one: "He ran like the wind"; "She took to racing as a duck takes to water." A metaphor acts as if the two compared things are identical and substitutes one for the other. Comparing the beginning of time to the beginning of a day, for instance, produces the metaphor "the dawn of time."Much has been written about the perils of mixed metaphors and their potential for inadvertent absurdity, as seen here: "This is a virgin field pregnant with possibilities" (cited by Fowler); "Yet the President has backed him to the hilt every time the chips were down" (cited by Bernstein). The shortcoming of such sentences is not so much that they mix metaphors as that they mix cliches. When neither of the metaphors in a sentence is hackneyed, you might just get away with it-as Shakespeare clearly did when he wrote, "Or to take arms against a sea of troubles."It should also be noted that you dont need two metaphors to botch a sentence. One will do if it is sufficiently inappropriate, as it was here: "Indiana, ranked the No. 1 swimming power in the nation, walked away with the Big Ten championship tonight" (Associated Press).
