'揭秘' (jiēmì) is a verb meaning 'to reveal a secret' or 'to expose hidden information.' Literally, 揭 (jiē) means 'to lift, uncover, or peel back,' while 秘 (mì) means 'secret' or 'mystery.' Together, they form a compound that emphasizes the act of bringing something concealed into the open—often with a sense of discovery, investigation, or public revelation. It's commonly used in media headlines, documentary titles, and scientific or journalistic contexts where previously unknown facts are disclosed.

The word carries a slightly formal or dramatic tone and often implies that the secret being revealed was deliberately hidden or not widely known. It’s frequently paired with nouns like '真相' (zhēnxiàng, 'the truth'), '内幕' (nèimù, 'inside story'), or '谜底' (mídǐ, 'solution to a mystery'). While it can describe everyday revelations, it’s most natural in contexts involving investigation, research, or exposés—such as medical breakthroughs, historical discoveries, or corporate scandals.
