Pronunciation

  • UK: /ˈθɹuː.pʊt/[1]
  • US: /ˈθɹu.pʊt/[1]

Etymology

It is formed from English through- + put,[2][3][4] after input and, in its industrial sense, output.[2][3][5] The OED takes the second element as the verb put and compares the phrasal verb put through,[2][5] while the Shorter Oxford takes it as the noun.[3]

Earliest recorded meaning

Capacity for work, energy, vigour, in Scots: 1808, in John Jamieson's Etymological Dictionary of the Scottish Language.[2][4]

Semantic evolution

The Scots word for energy has nothing to do with the modern sense, which was formed again on the model of input and output.[2][3] The amount of material passing through a process is first recorded in 1884, in the Transactions of the Mining Institute of Scotland,[2] though Etymonline and Merriam-Webster date the industrial sense to about 1915 and Dictionary.com to 1920–25.[4][6][5] From 1956 the word was used of the amount of data a computer processes in a given time.[2]
