Definition: Rudim, which was first used by French in the early 18th century, refers to a person who is not properly educated or well-prepared for his profession. The adjective Rudim means "uneducated" or "not well-equipped." It was often used as an insult and could have caused offense. In English, it's now more commonly used to refer to someone who lacks knowledge or education in their field of work, especially if they lack any formal training or experience. This term can be seen as a reflection of the idea that the educated are likely to better understand and handle complex problems, whereas those without formal education may struggle with these issues. In this context, Rudim refers to someone who lacks the necessary knowledge, skills, and experience needed in their occupation. It's important to note that the exact definition of Rudim can vary based on cultural norms, attitudes, and assumptions.
