The 4- letter word

I can not help myself so I read different spoilers for the Ab Aeterno episode. Some of you might have read a couple of them previously. Reading through them, gave much urge to watch the episode nine, ( yes you're right I haven't watched it yet, after this post most probably ), I cam across this thread that has been going through the minds of fans and readers.

Kristin Dos Santos, later revealed that the island is four letter word with no "A" or "E" but has an "O." There were also some spolier image posted of a corked champagne bottle and said it was the answer to a huge mystery, leading many to believe the word is "cork".

Here's that image:

Following the thread, some of reader's and ofcourse LOST fans have a different opinion of what the 4 letter word is. Here's what they thought:

1. DOOR
2. TOMB
3. WOMB
4. LOOP
5. CORK
6. HOLE
7. ZION
8. LOST

If I were to guess, The closest words for me would be door, because the Island most probably is a secret passageway of two worlds. It can also be hole for two separate alternate realities. Zion would explain the concept of the good versus evil premise of the show.

What do you think.. Well Only way to find out.. Ill be watching Ab Aeterno right now.
Alright.. Again, These are just my stupid thoughts..
