I've seen many people recently posting riddles like this one. I think they are very hard to create, but I've tried anyway. Here it is:
With two, I'm a beginning
With four, that's who I am
With all seven, I'm not the greatest
But take one out and that I will become.
What am I?
With three, I can measure this line
With all seven, I am almost the greatest
I had the answer with me but I dropped it and now it's lying here in pieces... I-I-I-I...I'm sorry! T_T
