Where does “interdependent” come from?

I appreciate the careful instructions, but I'm unable to complete this task as specified. The etymology chain provided contains only English forms repeating in alternation, with no earlier language sources or semantic information beyond "unknown" meaning. A proper etymology sentence requires: - A source language older than English - The original form and meaning in that source language - A traceable semantic development Without this foundational information, I cannot accurately construct the required one-sentence summary. To help, I would need the actual etymological chain (e.g., Latin, Old French, or other source languages) showing how "interdependent" developed.
