When used as adjectives, they are interchangeable; that is, they both have the exact same meaning. The only difference between the two is that they come from different origins, and contented is much less common than content in this regard. Basically contented is just a fancy way of saying content. The cat was content. The cat was contented. He was content knowing that his friend was safe. He was contented knowing that his friend was safe. However, content can also be used as a verb, which in the past tense would be contented. For example: The mother contented the crying baby. The boy contented his heartbroken friend.

Hello, Jill: (a) Most books and teachers say the two words are interchangeable. (b) So it doesn't matter which one you use -- you are as correct as anyone else!!! Even native speakers do not agree!!! (c) There is only one time when you MUST use "contented": when it comes before a noun: "Mona is a very contented person." "The milk from our farm comes from contented cows." (d) Some people feel that "content" is better for a permanent state/condition: A big newspaper has offered a good job to Tom, but he doesn't want it. He says, "I don't want to move to the big city. I feel/am perfectly content to stay in this small town until the day I die." (e) Some people feel that "contented" involves some kind of action/doing: I want our daughter to go to college. She doesn't want to. My wife and I are very unhappy. But yesterday she came to us and said, "I know how you feel, and you know how I feel. So I am going to do this: I am going to attend college for one year. If I like it, I'll continue; if I don't, I'll leave." I felt/was very contented with her decision. (3) Maybe the best thing for a learner to do is this: (a) Of course, ALWAYS use "contented" in front of a noun. (b) For ALL other sentences, use "content." You will always be "right"
