Respect for the country's flag, a desire to see your nation succeed, and a deep, abiding love of your country are all patriotic expressions, but being patriotic doesn’t mean you think your country’s perfect — just that you love it.
The Greek word patēr, which means father, was the basis for the word patris, or native land, and so patriotic came to mean "a love of country." In the 18th century, the word was formed from the word patriot by adding the suffix -ic, which turns a noun into an adjective. An example of a patriotic comment would be this one, by President Bill Clinton: "There is nothing wrong with America that cannot be cured by what is right with America."
