What did the people in the olden days call pajamas?

In olden days, pajamas were commonly referred to as "pyjamas," a term borrowed from the Persian Word "pāy-jāma," meaning "leg garment." They were often used to describe loose-fitting trousers worn by men and later evolved to include the full nightwear ensemble. In some cultures, they were simply called nightclothes or nightshirts, reflecting the variations in sleepwear across different regions.
