I was recently struck by how Google's terms of service are written in plain English legal writing:
https://www.google.com/intl/en/policies/terms/
Compare a contract term like this, often referred to as a severability clause (from Google's ToS): "If it turns out that a particular term is not enforceable, this will not affect any other terms."
With this, in traditional legalese: "If any term or other provision of this Agreement is determined to be invalid, illegal or incapable of being enforced by any rule or law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party."
Both have the exact same effect.
