You will probably need to define the context of the question; freedom does not exist in a vacuum apart from human beings. What things are relevant? Physical law? Coercion?
A determinist would say that physical laws deny freedom, while most people would say that being told "their family will be killed if they don't do X" would make a person less free (implying that there's a gradient in there somewhere), but someone who believes in libertarian free will would deny that any outside force can limit agency.
It's not too clear what is being asked if it's left so wide open. Kind of like asking "what is a game?" when the things people say are games are of such variety - chess, solitaire, hide and seek, "the game
", "playing chicken", etc that there is no necessary common denominator to identify them.
