A possible synonym for “combined” in the sense of conceptualization could be “integrated”.
When we say something is combined, we mean that different elements are brought together. “Integrated” has a similar meaning. For example, “The integrated system combines various technologies to provide a seamless experience.” Here, “integrated” shows that different components are merged in a way that functions as a whole, just like when we say something is combined.
Another synonym could be “unified”. “Unified” implies that disparate parts are made into one. For instance, “The unified approach combines different strategies to achieve a common goal.” This term emphasizes the act of bringing together different elements to create a single entity or concept, similar to “combined”.
“amalgamated” is also a good option. “Amalgamated” means to combine or merge into a single whole. For example, “The amalgamated company combines the strengths of two former rivals.” This word suggests a more deliberate and formal act of combining, but still conveys the idea of different elements coming together as in “combined”.
