Pronunciation

Theater, an early Middle English borrowing from French, originally had its primary stress on the second syllable: . As with many early French borrowings ( beauty, carriage, marriage ), the stress moved to the first syllable, in conformity with a common English pattern of stress, and this pattern remains the standard one for theater today: . A pronunciation with stress on the second syllable and the vowel , as or sometimes is characteristic chiefly of a nonstandard regional pronunciation in the United States that may be perceived as uneducated.

Etymology

Origin of theater

First recorded in 1325–75; Middle English theatre, from Latin theātrum, from Greek théātron “seeing place, theater,” equivalent to theā-, stem of theâsthai “to view” + -tron suffix denoting means or place

Explanation

If you are sitting in a crowd of people watching actors on a stage, you're probably in a theater. If the performance is projected on a large screen, you're in a movie theater. The Greek word for theater (theatron) comes from the verb theasthai, meaning “behold.” You are likely to behold a play or a film inside a theater. If you've dedicated your life to theater, you are probably an actor, director or playwright. Remember when you yelled “fire!” in a crowded theater and got arrested? That wasn't funny.
