Not really, terms should be historically constituted and there is a serious amount of self-codification among liberal theorists that makes the term extremely useful

There are only eight subspecies of liberalism that actually matter to real world politics, and they cover everything between anarcho-capitalists to DNC blue no matter who libs

Classical liberalism, utopian liberalism, social liberalism, neoliberalism, ordoliberalism, dirigisme, siege liberalism, and the mutated step-child fascism, these are the actual differentiations among the defenders of capitalism

There is only confusion on this matter because utopian, social and neo liberals successfully appropriated a mountain of socialist and anarchist lingo and incoherently applied it to themselves. I don't blame them, liberalism is deprived of any genuine vision of human progress or solidarity, it wears the liberatory spirit of anti-capitalist ideologies like a carnival mask and as a result millions of potential radicals end up confused as to where they stand in the struggle over capitalism
