A neologism is a newly coined word or expression that may be in the process of entering common use. These terms can arise from various sources, including technological advancements, cultural shifts, or creative language use. Neologisms often reflect changes in society and can help describe new concepts or phenomena that previously lacked specific terminology. Neologisms can be found in many areas, such as technology, pop culture, and social media. For example, words like "selfie" and "blog" are neologisms that emerged with the rise of digital communication. While some neologisms fade away, others become widely accepted and integrated into everyday language.
