A diaeresis may also be used in a like fashion, either to separate and mark off monographs (as in coöperation) or to signalize a vocalic terminal e (for example, Brontë). This use of the diaeresis peaked in the late 19th and early 20th centuries, but it was never applied extensively across the language: only a handful of diaereses, including coöperation and Brontë, are encountered with any appreciable frequency in English; thus reëxamine, reïterate, deëmphasize, etc. are seldom encountered. In borrowings from Modern French, whose orthography utilizes the diaeresis as a means to differentiate graphemes, various English dictionaries list the dieresis as optional (as in naive and naïve) despite the juxtaposition of a and i.
