I'm trying to make a deck based off of http://wiki.wareya.moe/Frequency%20lists , but I don't really see any explanation of each column anywhere.
Guessing the first one is some sort of frequency statistic, the second is if it is Japanese/Chinese origin(?), and 3, 4, 5, 6 contain verb/adjective/noun/pronoun etc and the 7th seems to contain the word in question. The rest I'm not really sure on, other than possible alternative readings but there seems to be duplicates all over the place in the same columns. Should I just strip everything except for the 7th and make a deck out of those or would I be missing anything important? That is assuming someone hasn't already made an anki deck out of this yet.
