The 'simple' future is so-named because it is a one-word tense. In other words, its formation is simple because there is no auxiliary. The stem of the simple future always ends with the letterr, which is the characteristic sound of the future and conditional tenses.

For a list of irregular verbs which form their future in the same way as regular verbs do, see future: regular.
