>>Hi everybody,
>>
>>The word "advice" is a noun, while "advise" is a verb. However, I see lots of messages, even from the native speakers, where "advise" is used as a noun. I'm wondering, what other examples for "c" in a noun and "s" in a verb exist?

>>Thanks in advance.

Don't pretend to defend the offence of using offense or defense in pretence of your defence.
