The spelling of the word "Bullwort" is quite peculiar. It is pronounced as "bʊlwɜːt" in IPA phonetic transcription. The initial "Bull" is a reference to the animal, but the ending "wort" is a bit more complicated. "Wort" in Old English meant "plant" or "herb," and is often used to describe a plant with medicinal properties. Therefore, "Bullwort" could be interpreted as a plant or herb that is associated with bulls or has medicinal properties that relate to them.
