Final answer:
Neologism is the creation of new and meaningful words, reflecting the adaptive nature of language to new concepts and societal changes.
Step-by-step explanation:
Neologism refers to the creation of new and meaningful words. It is a term often related to disrupted thought processes where an individual invents new words that may be meaningful only to them, often observed in psychiatric conditions like schizophrenia.
Language is a dynamic and evolving tool of communication, where new terms are constantly created and adopted into everyday usage, such as 'e-mail,' 'Internet,' and 'blogging.' These terms show how societies adapt language to new concepts and technologies. Within cognitive functions, language plays a crucial role in the expression and understanding of thoughts and identity.
