Strictly speaking a wat is a Buddhist sacred precinct with a vihara (quarters for bhikkhus), a temple, an edifice housing a large image of Buddha and a structure for lessons. A site without a minimum of three resident bhikkhus cannot correctly be described as a wat although the term is frequently used more loosely, even for ruins of ancient temples. As a transitive or intransitive verb, wat means to measure, to take measurements; compare templum, from which temple derives, having the same root as template.
