The word "retrain" refers to the process of teaching someone new skills or knowledge, especially when they are changing their job or profession. It involves providing additional training to help individuals adapt to new roles or tasks, often in response to changes in the job market or advancements in technology.
The word "retrain" is formed by the prefix "re-" which means "again" or "back," combined with the root word "train," which comes from the Old French "trainer," meaning to drag or pull, and ultimately from the Latin "tractus," meaning to draw or pull. Therefore, "retrain" literally means to train again.
