I first found "god" and "heaven" were among 1000 closest words, but didn't get what was going until I put "sake" (for god's sake). I realized this is a very common word and possibly also in common idioms and I eventually arrived at "everything", which was probably within top 10 I think. But it took me another 30+ trys to finally figure out that it was just a pronoun.

It's the same word for everyone once a day. So you just spoiled it for anyone who hadn't gotten it. Just FYI in case you want to edit.

Wow, I thought I had something going, and was even within the top 10 similar words, but in my opinion they are not very closely related at all.

Heres the the top list for me: https://imgur.com/AqmQl6A
