* Academic: "The professor presented a theoretical framework for understanding the social impact of technology."
* Science: "While the experiment was successful in theoretical terms, it remains to be seen how it can be applied in real-world situations."
* Business: "The company's theoretical profit margins were high, but they failed to account for unexpected expenses."
* Philosophy: "The philosopher explored the theoretical implications of free will."
* Everyday: "He had a theoretical understanding of how to fix the car, but he needed a mechanic to actually do it."
Remember, "theoretical" often contrasts with "practical" or "applied." It indicates something based on ideas, principles, or speculation, rather than real-world experience.
