As I progress in this program, lately I find I am beset with new vocabulary words that are kinda big and look similar to each other to me. It often helps me if there is something I can see about the word that reminds me of what it means. Here we have zufrieden. Is it a word made of smaller words? I know "zu." Google translate seems to say "frieden" means "peace" or "tranquility." Knowing that helps me relate better to "zufrieden" as "at peace" or "in a state of tranquility" or something and to remember it also when needed.
