Nomology is a term that is not as familiar to most people as other words in the English language. It is technically defined as the science of the laws, principles and customs that govern human thought, behavior and social organization. It is a word that is rarely used today and has become somewhat obsolete. There are several other words that can be used as a substitute for nomology, such as sociology, psychology, customs, laws, principles and regulations. These words encompass the same meaning as nomology and can be used in place of it in most instances. Thus, choosing the right synonym depends on the context in which it is used.
