(used with the past participle of another verb to form the passive voice, that is, to show the action of the verb has been done to the subject of the sentence): The policeman was shot. Your passports have been sent on. The verb be is special in English, first because it functions as an auxiliary, but also in the way it works as a main verb. It changes forms depending on its subject in the present and past tenses. Like the verbs do and have, the verb be comes first in questions that can be answered with the words "yes'' or "no'': Am I sure? Is she crazy? Are you there? Finally, the verb be can have the word not after it (again like do and have): She is not crazy. When be is used as a main verb, it seldom is used in the progressive tenses; we indicate this in this book by the symbol [not: be + ~-ing]. When talking about people's activity or how they behave, sometimes be as a main verb can take the -ing form of itself: I'm being careful (= I am acting in a careful manner); You're being so patient (= You are acting in so patient a manner). We do not use be in the -ing form to talk about states of the mind, or of feeling: I am happy now (*not:* I am being happy now); He is tired now (*not:* He is being tired now). be-, prefix. be- is attached to words to make verbs with the meaning "to make, become, treat as'': be- + cloud → becloud (= make like a cloud, hard to see); be- + friend → befriend (= treat someone as a friend). be- is also attached to adjectives and verbs ending in -ed to mean "covered all over; completely; all around'':be- + decked → bedecked (= decked or covered all over);be- + jeweled → bejeweled (= covered with jewels).
