A person or tool that fragments or breaks things into pieces; something that causes fragmentation.
From 'fragmentize' plus the agent noun suffix '-er', which creates nouns meaning 'one who does' or 'that which does.' The '-er' suffix is one of the oldest and most productive in English, forming both person and tool nouns.
Television was a fragmentizer of family time—it gathered everyone in one room but fractured attention, each person watching different channels in their mind; now streaming has completed that fragmentation, with each family member watching entirely separate content alone.
