The spelling of the word "re duplications" can be confusing due to the double letter "d" in "duplication." However, the spelling accurately reflects the pronunciation of the word, which uses a short "u" sound followed by a long "u" sound in quick succession. IPA phonetic transcription represents this as /riː djuːplɪˈkeɪʃənz/. "Re" is simply a prefix meaning "again," and is pronounced with a long "e" sound as /riː/.
