This is a place for things that like to watch.
watch (v.) Old English waeccan “keep watch, be awake,” from Proto-Germanic wakojan; essentially the same word as Old English wacian “be or remain awake” (see wake (v.)); perhaps a Northumbrian form. Meaning “be vigilant” is from c.1200. That of “to guard (someone or some place), stand guard” is late 14c. Sense of “to observe, keep under observance” is mid-15c.
