Repetition is the simple repeating of a word, within a sentence or a poetical line, with no particular placement of the words, in order to secure emphasis. This is such a common literary device that it is almost never even noted as a figure of speech. It also has connotations to listing for effect and is used commonly by famous poets such as
to one another that a disaster for one is a disaster for everybody.
(Natalia Ginzburg, The Little Virtues, 1962)
