Realis

现实（情态）

In semantics, a term used in the study of epistemic modality: in a realis assertion, a proposition is strongly asserted to be true, the speaker being ready to back up the assertion with evidence or argument. It is opposed to an irrealis assertion, where the proposition is weakly asserted to be true, but the speaker is not ready to support the assertion.

语言学中这个术语用于认识情态的研究：在现实断言中，一个命题被强断定为真，说话人随时能用证据或论据来支持这一断言。与之对立的是非现实断言，命题只是弱断定为真，说话人不准备提供证据来支持这一断言。
