THE MAZE 2: VOICE OF DARKNESS

The Maze 2
You have absolutley no idea what this room is because you can't see anything (YHANIWTRIBYCSA)

It's completely dark in here. Your only hint as to your whereabouts is the deep, dark voice that says:
 
"Answer the riddle I give to you
And you'll see where the light shines through
It's a little word I'm thinking about
With a letter repeated and one letter out
Of your following choices: N E T, L I S
Be correct and you might learn the secret to this quest."
 
You angrily tell the whatever-it-is that you don't speak Spanish.
 
"Okay, okay, in simpler terms, you have six letters: N, E, T, L, I, and S. Spell me the word I'm thinking of using those. I'll be generous and give you six tries."

Luckily, you only know six words that use all those letters, so this one's pretty much already answered for you. It's just the process of elmination. Pick a word.
