Question

what does the term fratinity signify in the preamble

Answer 1

It was, indeed, a way of life, which recognizes liberty, equality, and fraternity as the principles of life and which cannot be divorced from each other: Liberty cannot be divorced from equality; equality cannot be divorced from liberty. Nor can liberty and equality be divorced from fraternity. Without equality, liberty would produce the supremacy of the few over the many. Equality without liberty would kill individual initiative. Without fraternity, liberty and equality could not become a natural course of things.
