the ACI (accusativus cum infinitivo, as this construct is called in
Latin) exists in several other languages that use
declensions, most notably
Greek.
It is generally used to express indirect expressions and therefore usually follows verbs of saying, thinking, fearing, feeling etc. In Greek there is also a form of independant ACI, in which the infinitive is the actual subject of the sentance something along the lines of: to be wise is good)
