Seven follows suit,
Eight go in line,
Combined, 9 leave the queue.
Leaving i e, once removed, rearranged casts light upon the answer.
What am I?
I am a word.
Pay attention to punctuation.
Two of the three numbers in the riddle are not used like the other.
The sequence of numbers and their progression is NOT a nod towards the answer. For instance they do not reference something which is versioned (think computer software/OS) or of something that is incrementally changed (playing cards). This was intentionally misleading in the riddle to add to its complexity but I am revealing since all answers up to now have read in to it, distracting from the actual method to solve it.
Note: This riddle was previously closed for being "unclear" as to what it was asking. I have added a new tag, "word" (which is a hint in itself that I was trying to avoid originally), clarified the title and added the question "What am I?" at the end of the riddle. If this still is not clear enough please comment and suggest ways in which I can make it clearer. I am being cautious being overly specific as it is a short riddle and saying too much may reveal the answer.
