Usage notes 
- The pronunciation /ʃɔɹtˈlaɪvd/ (the second syllable rhyming with hived) is more consistent with the etymology (since the term comes from the noun life rather than the verb live), and was formerly more common; however, the pronunciation /ʃɔɹtˈlɪvd/ (the second syllable pronounced as the verb lived) is more common today.
