The paper demonstrates the possibility of deriving, from the Correlational Grammar developed solely for the purpose of automatic sentence analysis, a classification of words that could be useful in language analysis and language teaching. A group of some 90 frequent English adjectives serves as example; they are sorted into ten classes according to their behavior in strings of the type "John is easy to please,""John is eager to please,""John is likely to please," etc. It is suggested that the members of a least some of these classes show common semantic features that could be used to obtain intensional definitions which would theoretically confirm the empirically derived extensional definitions supplied by correlational grammar.
