 PapirusTextPos will take into account \n as a line break (or multiple line breaks)
 Meaning text will be aligned to the X position given, it will not return to x=0 for the start of the next line.
 
-WHen the text is longer than will fit on a single line, PapirusTextPos will break the text in multiple lines.
+When the text is longer than will fit on a single line, PapirusTextPos will break the text into multiple lines.
 You can limit the number of lines by specifying the parameter `maxLines` in the `AddText()` method.
 
 When using the PapirusTextPos, in either mode, setting the "partialUpdates" property to True will cause partial updates to be done, meaning only the section of the PaPiRus screen that has been changed will be updated.  These can be vastly quicker than a full update for each piece of text.
