Some of you might have encountered plurals such as bok böcker, similar to English goose geese, so I thought I’d post this list I made a while back. I think it’s near-complete. For historical reasons, all these words are en-words, except for land and stånd. Beware of that some of these words are very uncommon so you will likely never encounter them, however, many are extremely common.
