My deck of words I come across when reading and need to learn properly. I try to add words even when I am only slightly unsure as to the exact definition. Other advanced English vocab decks generally contain too many words I already know, so I saw no choice but to slowly build my own.
Format is not very consistent. Some words contain example sentences, some don't. Some have stress/pronunciation. The deck is made for personal use, but may be useful to someone out there.
