bulla (Latin)
Where does "bulla" come from?
The Latin noun 'bulla' has an uncertain origin, but it is ultimately considered to be onomatopoeic[1]. Scholars suggest it may stem from Gaulish, drawing from the Proto-Indo-European root '*bew-' meaning 'swelling', which also relates to Middle Dutch 'puyl' meaning 'bag' and Lithuanian 'bule' meaning 'buttocks'[1]. Alternatively, it may derive from '*bʰel-' meaning 'to blow, inflate, swell'[1]. Over time, the Latin word came to describe a bubble, a swollen object, a protective amulet worn by Roman children, and eventually a round metallic seal used on medieval documents[1].
