orthography

It's a damn poor mind that can only think of one way to spell a word! That quote, ascribed to Andrew Jackson, might have been the motto of early English spelling. The concept of orthography (a term that derives from the Greek words orthos, meaning "right or true," and graphein, meaning "to write") was not something that really concerned people until the introduction of the printing press in England in the second half of the 15th century. From then on, English spelling became progressively more uniform and has remained fairly stable since the 1755 publication of Samuel Johnson's Dictionary of the English Language (with the notable exception of certain spelling reforms, such as changing "musick" to "music," that were championed by Noah Webster).
