Orthography is an official or correct way to write a particular language. It includes rules of spelling.[1] Orthography may also include rules about punctuation, capitalization, and diacritics (e.g. accents). In English, spelling is a problem for all learners, and is the main issue in orthography.
Some languages have someone to decide the correct spelling, such as the Académie française. English does not. English orthography was the work of the early printers. They had to decide how particular words would be spelled in their books. Gradually the number of alternative spellings began to drop. The word which is "merry" today was spelled in about 30 ways in written sources from the 9th to the 16th century.[2]p970
