If one considers how a term like ‘tall’ is ordinarily employed in the

English language then it is clear that its meaning is ambiguous. Quite

simply, its meaning varies relative to the context in which it is

employed. For example, compared to other buildings in the United

Kingdom, the Canada Tower at Canary Wharf, in London, is tall. But if

you ask whether it is tall compared to the Empire State Building in

Manhattan, you will get the answer that it is not.
