An Academic Look at IOU

When IOU is shorthand for "I owe you" and followed by a direct object (i.e., the thing owed), it is most often used as a standalone declarative sentence (i.e., a statement of fact). However, when IOU denotes a physical slip of paper, it is used as a noun.

The term IOU is commonly written with full stops / periods (I.O.U.). This practice peaked in the 1930s but is now waning. In other words, more people are writing it without full stops / periods. [click here for evidence]
