What does the suffix ism mean in the word capitalism

The act or condition of an economic and political system.

Explanation: Suffixes change the meaning of a word.  In this case, "capital" is the country's trade and industry (what we would use to earn money for our country).  By adding -ism, you are changing the meaning to being an economic system, or rather, the way (act of) making money.

that is the way of a cheater and cheaters get nothing but bad grades and in trouble.
