Aurora's word prediction also supports grammatical rules.
Below you can see the rules in action, they know for example that people do not often use two
inquisitives in a row like "what what" or "who who."
You can see when you type the first "w" you get words like "who", "what", "where", "when",
and "why". After you select one of these words, and type the "w" for would, the grammatical rules cause
Aurora Prediction not to show those inquisitives again.
