Where does “XXX” come from?

I need to flag an issue with this chain before writing the sentence. The chain provided contains a logical problem: it shows both "Latin ecstasis" and "Latin crux" as sources, but these are contradictory paths. Additionally, "Old Irish cros" and "Proto-Indo-European (s)ker-" don't connect logically to "Latin ecstasis" (which comes from Greek ἔκστασις meaning "standing outside"). The chain appears to conflate two separate etymologies: 1. A Greek-Latin path (ecstasis → crux) 2. An Irish-PIE path (cros → s)ker-) Could you clarify the intended etymological chain? Once confirmed, I can write an accurate one-sentence summary following your rules.
