Hi Guys
When we use Rikaichan, we see the common words marked with (P).
Is there any way to get a list of all such words?
If the list is in order of usage frequency, it is even better.
I am sure some of you have encountered the same thought before.

use this deck http://forum.koohii.com/thread-12757.html
and search for the cards tagged with "common" That should be more or less all of the common works, with an occasional obscure word might slip through.
(Ref　大喪)

Downloaded that deck now.
Thanks.
I extracted all the cards as notes into text file.
Pasted them into excel to see what was the data.
There are too many tags in the column which contains "common" tag.
Should we assume that all those tags imply common? (like jlpt.. core..)

Common is relative. E.g. apparently 踏み絵 is frequent enough to be considered common.

I wouldn't trust that list of words to be honest. There doesn't seem to be any good manually edited word lists past 10k. Trust me I've looked.
