 The words employed in a contract cannot be viewed in isolation, divorced from the matrix of facts in which they are set, if the intention of the parties is to be ascertained.While the first step in construing a contract is still to ascertain the ordinary, grammatical meaning of the words used, “it should be recognised that very few words have a single meaning, and even the ‘ordinary’ meaning of a word may vary according to, or be qualified by, the factual context in which it is used.” A court should therefore be alive to the various possible meanings of the words, and should not approach the matter on the basis that a particular meaning predominates.It should also have regard to the nature and purpose of the contract, as well as the context of the words in the contract as a whole.
