How do I get dictionary suggestions while typing?
if you're willing to switch keyboards, you have several incredible options. 


SwiftKey has (by far) the best word prediction so far, and tracks how much it improves your typing speed, which is around 30% for most people.
FlexT9 has some great features (including traceType, like Swype), and pretty good word prediction, but not quite up to par with SwiftKey.
TouchPal is supposed to be the next revolution in keyboards. It combines the first two strategies (word prediction and traceType) for incredibly fast input. As of now, it does not support traceType, only word prediction. But look for the update soon ;)


These are my favorites, the first two are paid and the last is free, but you might be able to find free or trial versions of the other two. Let us know if there's anything else we can clear up for you!
