Dictionary
For many languages, iPod touch has dictionaries to help you type. The appropriate
dictionary is activated automatically when you select a supported keyboard.
For a list of supported languages, see www.apple.com/ipodtouch/specs.html.
iPod touch uses the active dictionary to suggest corrections or complete the word
you’re typing. You don’t need to interrupt your typing to accept the suggested word.
