Heyo, friends! Welcome back to my quiz!

I want to note that I do not wish for the dirty version of the answers. I want clean answers, so please refrain from submitting a cuss, for example, because that's not what I'm looking for. Thanks.

This time, this riddle will be a rhyme and only have clean possible answers because my previous questions have been just "affix and suffix" and have dirty possible answers (which are wrong of course,) and I was told that I should shake it up a bit.

For new contestants, we'll list all of the riddles from the previous parts of the quiz so that "no one is confused" as someone said. Okay enough of that.

Question #1: What is a word that starts with the letter "H" and ends with "ELL?"

Question #2: What is a four-letter word that ends with "MN?"

Question #3: What is a seven-letter word that starts with A and ends in the word "Hole?"

Question #4: What is a word that starts with B and ends in the word "Itch?"

Question #5: What is a word that starts with S and ends in the word "Hit?"

Question #6:

I belong in a book,

and I do have a twin.

Readers start with me

then move on to him.

In my direction,

it's the opening again

In his direction,

we end with Amen.

What am I?

33% of participants have answered correctly.

UPDATE: There was one answer for this, but after someone found another great answer, there's now TWO answers. Can you find them both?

UPDATE #2: I changed the first line from "text" to "book" because I thought "text" was too vague for the answer.

Good luck, readers! :)
