Etymology

The word "underscore" combines "under" (from Old English under, meaning "beneath") and "score" (from Old Norse skor, meaning "a mark or incision"). Originally, it referred to a literal line drawn beneath text for emphasis. Over time, it evolved metaphorically to signify highlighting importance in speech or writing. The morphemes retain their original spellings, preserving the word's logical construction.
