In the word "misplace," we need to find pairs of letters that have the same number of letters between them as they do in the English alphabet. The pairs are: (m, p), (i, s), and (l, e). Each of these pairs has 2 letters between them in the alphabet, matching the spacing in the word. Thus, there are three such pairs.
