Etymology
the word 'backlighting' is a modern english compound formed from native germanic elements. the first element, 'back', derives from the old english 'bæc', a word of proto-germanic origin referring to the rear part. the second element, 'light', originates from old english 'lēoht', tracing back to the proto-germanic 'leuhtą' and ultimately to the proto-indo-european root 'lewk-', meaning 'light' or 'brightness'. the suffix '-ing' is a productive noun-forming suffix in english. the term logically and transparently describes the technique of placing illumination behind a subject, a concept that emerged with advancements in visual arts and technology.
