Why doesn't spell check know how to spell Theatre?

answers1: "Theatre" and "theater" mean the same thing and in England
people use "theatre" as well, whether it's the artform, place or
building. "Theater" is the American spelling. <br>
<br>
You can change the language defaults in MS Word to spell it the way you like.
answers2: I didn't know that !! I spell it theatre!! It doesn't even
look right to me !! Maybe it's a french interpretation that we use!!
Like the word colour spell check spells it color !! They also may do
this because over the years we have been taught to spell it the way it
sounds so it is easier !!
answers3: You are actually incorrect. <br>
Cinema is the British Term for Movies. <br>
Theater is the American spelling for the building a play takes place
in as well as the art form. <br>
Theatre is the British spelling for excatly the same thing. <br>
Both are correct.
answers4: According to my dictionary theater is the US spelling. In
Canada I'm used to theatre. And I believe it's cinema and yes it is
chiefly British.
answers5: Webster's New World lists both spellings. I favor 'theatre'
only because it resonates with the longer 'theatrical'. (As opposed to
'theaterical', which is not only clumsy but a non-word - like
'cinama', rather than 'cinema').
answers6: Theater is the physical building. Theatre is the artform.
answers7: "Theatre" and "theater" technically mean exactly the same
thing. US derivations of English words often change spellings over
time because we speak differently. Other examples in this category
include centre/center, fibre/fiber, spectre/specter, litre/liter, etc.
However, the theatre subculture in the US has sort of assigned meaning
to the two spellings, calling "theatre" the action of the performance
and production and "theater" the physical building in which the
production is performed. Hope this is helpful! :)
answers8: hahaha that's pretty funny. LMAO <br>
theatre and theater
answers9: To me Theatre is where you go to see live on stage - theater
is the american way of saying cinema but i think it can also mean the
stage. I'm not really sure but i always spell it theatre and cinema
(i'm english).
answers10: According to the Oxford English Dictionary, they are the
same word, just alternate spellings, meaning the physical place.
