Penlight → It is formed from "pen" (from Latin *penna*, meaning feather or quill) and "light" (from Old English *leoht*, meaning illumination). The word "penlight" refers to a small, portable light that resembles the shape of a pen, used for illumination.
Think of a 'pen' as something that writes and 'light' as something that illuminates. A penlight is a small light that you can easily carry, just like a pen.
