Morphology

SIU = S + I + U

This is an initialism (letters stand for 'Special Investigations Unit'); the letters do not function as English morphemes and the meaning cannot be derived by knowing English roots alone.

Etymology

SIU is an abbreviation made from the first letters of Special Investigations Unit, where 'special' means serious, 'investigations' means careful checking, and 'unit' means a team, so SIU is used for teams that investigate complex or suspicious cases.
