Deorsum is a Latin word that means "downward" or "below." In IPA phonetic transcription, it is spelled [dɛˈɔr.sʊm]. The initial "d" is pronounced as a voiced dental plosive, followed by an "e" pronounced as an open-mid front unrounded vowel. The stress is placed on the second syllable, which is pronounced with an "or" sound, followed by an "s" pronounced as an unvoiced alveolar fricative. The final syllable is pronounced with a short "u" sound followed by an "m" pronounced as a bilabial nasal sound.
Downward, turning downward.

The word "deorsum" originates from Latin. It is a combination of two Latin words, "de" meaning "down" or "from" and "orsum" meaning "upward" or "toward the top". When these words are combined, "deorsum" is formed, which translates to "downward" or "toward the bottom" in English.
