headlining

The word 'headlining' is a modern compound verb formed from the noun 'headline'. The term 'headline' itself emerged in the late 19th century from the journalistic practice of placing the most important summary of a news story at the 'head' or top of a column of text, which was a 'line' of type. The 'head' element, from Proto-Germanic, carries the ancient sense of the uppermost or foremost part of the body, metaphorically extended to mean the most important item. The 'line' element, tracing back to Latin 'līnea' (a linen thread), evolved to signify a row of written words. Thus, 'headlining' logically describes the act of being placed in that foremost textual position, a concept later extended from print media to entertainment, where the top-billed performer is figuratively the 'head' of the show's promotional 'lines'.
