In line with current thinking in transformational grammar, syntax as a system can and should be studied before a study is made of the use of that system. Chomsky's lexical redundancy rule is an area for further study, possibly to come closer to defining and achieving explanatory adequacy. If it is observed that English nouns come in two types, with the members of one set differing from the members of the other by a constant phonological and semantic increment, it is possible to note a generality by choosing one of each pair of nouns to represent both in the lexicon and then construct rules allowing for the general similarity. When all the regular relations between lexical items are expressed, the result is a set of simplified lexical entries, each one an abbreviation for one or more fully specified lexical items, and a set of redundancy rules expressing the relevant generalities and subgeneralities of the lexicon. Given here are the major types of lexical redundancy rules for English nouns and what they can accomplish. Actual rules and examples are provided. A list of references is included. (Author/VM)
