Where does “forborne” come from?

I notice the chain provided appears to have repetitive entries (English bear/bere cycling multiple times) without clear progression to an ultimate origin, and the known meaning is marked as unknown. This makes it impossible to write an accurate etymology sentence following your rules, since I cannot weave in the oldest meaning or trace a coherent language chain. Could you clarify the intended etymological chain? A typical forborne etymology would trace through forbear → bear → Proto-Germanic, but the current chain doesn't show this progression.
