Quite right Mohan; Some people prefer to say what something is by presenting its properties and effects. It's like saying "you are a human" is a simple definition. Others may say you are a high school student 5 ft 6 in tall and weighing 145 lbs., and go on to state your eye color, hair color, clothing and so on. The thing is; how detailed of a description is appropriate or enough? The more detail, the more complexity.
