The term "nerd" refers to a person who is deeply passionate about specific subjects, especially those related to technology, science, or academics. Nerds are often characterized by their intense focus on their interests, which can sometimes lead to social awkwardness or being perceived as "uncool." While the word was traditionally used in a derogatory manner, it has been embraced by many as a badge of honor, representing enthusiasm and expertise in their fields.
The word "nerd" is believed to have originated in the early 1950s. It is said to have been popularized by Dr. Seuss in his book "If I Ran the Zoo," where a character named "Nerd" was introduced. The term evolved in use, becoming synonymous with someone who is overly intellectual or socially inept.
