It is called an acrostic to that linguistic composition, whether poetic or not, whose initial, central or final letters, together with others organized vertically, form a word or phrase. By default, this newly formed word is called an acrostic. This type of poem enjoyed great popularity during literary times that were characterized by searching, as in the baroque.

Currently, acrostics are considered as ingenious forms of entertainment, similar to crossword puzzles, sudoku puzzles and other creative thinking games; it is common to find them in magazines, weeklies, newspapers and brochures.

According to historical research on this practice, acrostics were made, for the first time, by the Castilian poets. These transmitted their knowledge to the Provençal poets, (who at one time were considered the first), a group that was responsible for making this style popular. From then on, it only took a little ingenuity and talent to make an acronym. Some artists preferred to place the letters that form the words at the beginning, others in the middle of the text and many more at the end; however, the predominant format was the former. It is known that, on some occasions, this was used to enrich the poem or leave some additional messages.

Throughout history, a considerable number of popular acronyms have emerged, such as “El bachiller”, which can be read in the prologue of “La matchmaker”, a novel by Fernando de Rojas, titled that way because it is the phrase that produced with the first letters of the poem. Luis Tovar also owns one of these precious pieces: a poem whose purpose was to spell “Francisca”, but ends in “Francyna”, and decides to include, in the middle of the creation, other names such as Eloísa, Ana, Guiomar, Leonor, Blanca, Elizabeth, Helen and Mary.
