Beneath these popular images, spelling is a human literacy ability that reflects language and nonlanguage cognitive processes. This collection of papers presents a sample of contemporary research across different languages that addresses this ability. To understand spelling as an interesting scientific problem, there are several important perspectives. First, spelling is the use of conventionalized writing systems that encode languages. A second asks how children learn to spell. Finally, from a literacy point of view, another asks the extent to which spelling and reading are related. In collecting some of the interesting research on spelling, the editors have adopted each of these perspectives. Many of the papers themselves reflect more than one perspective, and the reader will find important observations about orthographies, the relationship between spelling and reading, and issues of learning and teaching throughout the collection.
