- A prefix signifying one, once; as in uniaxial, unicellular.
The prefix uni- often means "characterized by one thing," but in this word and in the word unisex it is more like "both."
The MacBook Pro line in early summer 2011 received new Sandy Bridge processors to accelerate proficiency with no aesthetic differences from previous uni- body design.
Just as the uni- prefix implies arrogance, multi- implies meekness, requiring Clinton’s secretary of state, Madeleine Albright, to come up with a toughening modifier: “assertive multilateralism.”
