Does theater have to be capitalized in a sentence?

Answer 1

The noun theater is only capitalized if:

- it refers to a course of study at a school (e.g. Theater, Dramatic Arts)

- it is included in a proper noun (e.g. the Globe Theater)

- it is the first word in a sentence

Answer 2

No. Strictly, the words are common nouns and don't need it. People sometimes use it in the sense of a title, though, and it's not really wrong to capitalise here.

For instance, no one is likely to quibble about something like this:

Toytown Academy is seeking to appoint a well qualified teacher to join the Theatre Department of this thriving school.

Answer 3

No, "theater" does not have to be capitalized in a sentence unless it is being used in a proper noun or as part of a specific title (e.g., Broadway Theater).
