So this is today's study card, or at least the first one of the day. Usually these are the words I am having the hardest time with from my Anki study deck. For some reason, these all seem to be adjectives and adverbs today. That's not always the case; they can be any part of speech. Nouns seem to be the easiest to learn, as a general rule. Maybe that's because an object can be pictured. But even abstract nouns are easier than verbs. Verbs seem to be the hardest. Usually I will make separate cards for just verbs.
I always "learn" the words and then find that a month later I will have forgotten some of them. So that's where spaced repetition comes in, to put them at the proper spacing. All of these words are words that I supposedly "learned" previously. But I suspect the problem is not one of memory storage, it is one of memory retrieval, because often the stuff I am searching for will just suddenly pop into my head.
Then at some point I try to collect the cards from the past week or two, go over them again, and pick out the hardest words that I am still having trouble with and put them on new cards.
