である (dearu)

is; are; to be

Meaning & usage

である means is or are and states what something is, such as its identity, type, or quality. It is the formal written counterpart of だ and です, so it appears in textbooks, papers, definitions, and official statements. It follows a noun or a na-adjective directly, as in 学生である or 静かである, and its past form is であった. It sounds stiff in everyday conversation, where だ or です is expected instead.
