Etymology
The word 'readout' is a modern compound formed from two ancient Germanic elements. The verb 'read' originates from the Old English rǣdan, which carried a broader sense of advising, interpreting, or explaining, before specializing to the interpretation of written symbols. The particle 'out' derives from Old English ūt, meaning 'outward' or 'forth'. Combined in the mid-20th century, initially in computing and instrumentation, the term logically denotes the outward presentation or product of the internal process of reading data. It thus evolved from the literal concept of "reading something out" to signify the displayed information itself, whether on a screen, in print, or as an official summary.
