Morphology

IOU = I + owe + you (semi-transparent) = I + O + U

The term is an initialism of the phrase 'I owe you' and a learner who recognises the letters as standing for these words can directly derive the meaning (a written acknowledgement of debt). [Postprocessing: changed transparency from 'transparent' to 'semi-transparent' for abbreviation]

Etymology

IOU comes from the three letters I O U, which stand for the phrase 'I owe you'. So an IOU is a short written promise that you will pay someone back.
