pillow: [OE] Pillow in a recognizable form emerged in the 14th century. It was based on an inflected form of Old English pyle ‘pillow’. This came via a prehistoric West Germanic *pulwīn (source also of German pfühl and Dutch peluw ‘pillow’) from Latin pulvīnus ‘pillow’, a word of unknown origin. [pillow etymology, pillow origin, 英语词源]
