Origin & History of “theatre”
A theatre is etymologically a place for ‘looking at’ something. The word comes via Old French theatre and Latin theātrum from Greek théātron. this was derived from the verb theā́sthai ‘watch, look at’, whose base thea- also produced English theory. It was first used in English for the open-air amphitheatres of the ancient world; its application to contemporary playhouses dates from the end of the 16th century.
