How to block short keywords in Adwords?

Question:

I want to block the search term "South Africa" but not any search term that has more then South Africa .. example South Africa Information/products/trips/flights or anything like that..  

I just don't want me ad to be shown if the user is just searching for "south africa"  but all my keywords contain the words South Africa  

If i add "South Africa" as a negative exact, will it block South Africa Products for example?   

Answer:

Negative exact will only block [South Africa] and nothing else. Negative phrase will block other terms containing "South Africa".

So if you want to block the term [South Africa] and only that term or Search query then add it as a negative exact.
