The correct spelling of the phrase "be excluded" is with a single "c" instead of "be exclude." This is because "exclude" is spelled with a single "c," and "excluded" is its past participle. When using "be" as an auxiliary verb, we add the past participle to create the passive voice. Therefore, "be excluded" is the correct spelling. Using the International Phonetic Alphabet (IPA), the pronunciation of "be excluded" would be as follows: /bi ɪksˈkluːdɪd/.
The term be exclude does not have an established etymology, as it is not a standalone word or phrase in English. However, if you are referring to the verb exclude, its etymology can be traced back to the Latin word excludere, which is a combination of ex (meaning out) and cludere (meaning to close). Therefore, exclude essentially means to close out or to keep out.
