A nerd is generally a term used to refer to a person who is intellectual, undesirable, and uninteresting. Geek is used to referring to a person who has a preoccupation with a specific field or subject and is very enthusiastic about his area of interest. A dork is utilized to refer to a person who is tedious and unwise. However, they are also interesting people. Dr. Seuss first uttered the word nerd in 1950. It appeared in his story, “If I ran to the zoo.” He depicts a character that is a grumpy humanoid with wild, unruly hair and sideburns. This kind of style is synonymous with the word nerd. Geek was initially used as an insult. The term was used to describe the circus performers who do crazy stuff. Dorks try to relate with others, but their efforts are of no use since nobody wants to talk to them.
