"わからない言葉を私の後に繰り返さないでください。"

Simplified Meaning:

When people say things without really understanding what they mean, it can create confusion and problems. Imagine a child repeating a difficult word they heard from an adult, like "photosynthesis," without knowing it’s about how plants make food from sunlight. They might use it wrongly or not learn anything useful. In everyday life, it's important to know the meaning behind the words we use. If someone says a medical term without understanding, they might spread wrong information, causing worry. By making sure we understand, we can communicate clearly and help others get the right message. For instance, in a job meeting, using complicated business jargon without understanding could lead to mistakes or misunderstandings in a project. Learning the true meaning of words helps us make better decisions and express ourselves properly. So, before repeating what we hear, we should try to understand it first.
