"Oleum bubulum" is a Latin phrase used to describe a type of oil extracted from bulls. The word "oleum" is spelled with the IPA phonetic transcription of /ˈɒliəm/, with the "o" pronounced like "ah" and the "e" like "uh". "Bubulum" is spelled with the IPA phonetic transcription of /bjʊlʊm/, with the "u" pronounced like "oo" and the "l" strongly pronounced. Together, the phrase is pronounced as "oh-lee-uhm boo-bu-luhm". Its unique spelling is in part due to the pronunciation rules of Latin, which differs from modern English.

The phrase "oleum bubulum" does not have a clear etymology as it does not correspond to a specific word or term. However, we can analyze the individual words "oleum" and "bubulum" to understand their origins.
1. Oleum: The word "oleum" comes from the Latin language, where it means "oil". In Latin, "oleum" is derived from the Greek word "elaion" (ἔλαιον) with the same meaning. Ultimately, both Latin and Greek borrowed this term from the Ancient Egyptian word "ila" which also meant "oil".
2. Bubulum: The word "bubulum" is derived from the Latin language as well. In Latin, "bubulum" refers to a neuter noun form which means "a bullock" or "a draught ox".
