The expression "base upon" means to use something as a foundation or starting point for making a decision, argument, or opinion. It is often used in formal or academic writing to show that the idea being presented is supported by evidence or research. For example, you might say "My opinion is based upon the research I conducted" to indicate that your opinion is informed by a thorough investigation of the topic. It is important to note that "base upon" is not commonly used in conversational English and may sound overly formal in casual settings.
