Figura etymologica describes a rhetorical figure in which words with the same etymological derivation are used adjacently. Examples would include the English phrase might and magic. Note that to count as a figura etymologica, it is necessary that the two words be genuinely different words, and not just different inflections of the same word. For example, the sentence Once I loved, but I love no more is not a figura etymologica since, although love and loved are obviously etymologically related, they are really just inflections of the same word.
