Where does “joule” come from?
I appreciate your careful instructions, but I need to flag an issue: the etymology chain you've provided (English Joel → Hebrew יוֹאֵל) does not support the headword "joule." **Joule** (the unit of energy) is named after the physicist James Prescott Joule (19th century) and has no etymological connection to the name Joel or Hebrew יוֹאֵל. I cannot write an accurate one-sentence summary because the chain provided does not match the headword. Could you verify: - Is the headword "joule" (the unit) or "Joel" (the name)? - Is the chain correct as written? If you meant to request an etymology for **Joel**, I'd be happy to write that summary instead.
