G3 and others were merely pointing out the correct grammar. Ironically, the quote you posted and the words you highlighted make the point.
In Australian English, the words "licence" and "license" have different meanings.
The word "licence" is a noun. "Here is my licence, officer,"
The word "license" is a verb. "I license you to copy my software."
As Kaz points out, the word "practice" is a noun. "My dental practice is lucrative."
The word "practise" is a verb. "I'm going to practise soccer this afternoon."
And a favourite of mine...
The word "dependant" is a noun and the word "dependent" is an adjective.
"I have two dependants: Mary and John. That's because they are dependent upon me for food and shelter."
