General first-order languages When translating from English to FOL, you will occasionally have for your use a predefined set of names and predicates such as those used by the Tarski’s World program. At other times, you will not have an available set of names and predicates to use in translating from English to FOL. In such instances, you will have to design a language that will allow for such translations. Consider the following sentence: Claire gave Scruffy to Max. To translate this sentence into FOL, you must introduce both the required individual constants as well as some sort of predicate symbol to describe the relationship among the various individual constants. You might, for instance, decide to use the binary predicate GaveScruffy(x, y) meaning x gave Scruffy to y . The original sentence would then be translated as follows: GaveScruffy(claire, max) This predicate symbol will allow you to translate any English sentence in which someone gives Scruffy to someone else, but how might you translate the following? Claire gave Carl to Max.
