Why does my iPad automatically capitalise Bono but not the edge?
English is hard.

One is easily distinguishable as a proper noun. Bono is not a common word that would be anything other than a name. Like Sally or Andreas. The OS can capitalize occurrences of Bono with a high degree of confidence that you were referring to a proper noun.

The other is not easily distinguishable as a proper noun. There is no way to tell if the sentence:


  I played guitar near the edge


is referring to you playing guitar near a precipice or near another human who has the legal name Dave Evans.

You can create a text shortcut to automatically expand a text snippet you enter like tedge to The Edge if you like. You can find shortcuts in the Settings app under General &gt; Keyboards &gt; Shortcuts.
