1. Introduction: The addition of a characteristic to a basic subject idea or an isolate idea leads to the addition of an array. The addition of an array implies the addition of a further division of a basic subject or an isolate idea as the case may be. Any isolate idea taken along with its succession of sub isolates is also an isolate idea. The succession of the isolate idea from the first to the last reached in this process is denoted by the term “chain of isolate idea”. A chain may similarly be formed in respect of basic subject idea.
4. Examples: Asia, India, Assam, Kamrup, Guwahati is a chain of isolate idea.
