Zeugma is a figure of speech in which one word, usually a verb or adjective, is linked with two other words, but fits each in a different way. Often the shared word works literally with one part and figuratively, humorously, or surprisingly with the other, creating a compact, witty, or layered effect.
Writers sometimes use zeugma to speed the line, sharpen contrast, or make one phrase carry more than one meaning at once.
Example
She carried the flowers and the weight of yesterday.
The verb carried applies literally to the flowers and figuratively to the weight of yesterday.
[n] use of a word to govern two or more words though appropriate to only one; "`Mr. Pickwick took his hat and his leave' is an example of zeugma"
