I am trying to understand the following phrase:
Du gibst das Leben mit einem klaren Sinn, beendest das Verlorensein, schenkst einen Neubeginn.
But I couldn't see the meaning of "Verlorensein". I found that there is a verb "verlieren", which means to lose, and I suspect that sein is a sufix here that converts this verb into a noun, but I don't know.
Any help is appreciated.
