‘WYSIWYG’, pronounced ‘whizzywig’, means What You See is What You Get, this is computer lingo…
This is generally thought to have been coined from the phrase and in reference to the graphical computer user interfaces that were emerging from Xerox PARC in the 1970s, but it isn’t known who first used the acronym in that context. The first such reference that I can find comes surprisingly late, in Byte magazine, April 1982:
‘What you see is what you get’ (or WYSIWYG) refers to the situation in which the display screen portrays an accurate rendition of the printed page.
