syllepsis

Charles Dickens made good use of syllepsis in The Pickwick Papers when he wrote that his character Miss Bolo "went straight home, in a flood of tears and a sedan chair." Such uses are humorously incongruous, but they’re not grammatically incorrect. Syllepsis as defined at sense 1, however, is something to be generally avoided. For example, take this sentence, "She exercises to keep healthy and I to lose weight." The syllepsis occurs with the verb exercises. The problem is that only one subject, "she" (not "I"), agrees with the verb. The word syllepsis derives from the Greek syllēpsis, and ultimately from syllambanein, meaning "to gather together." It has been used in English since at least 1550.
