Morphology

underground = underground (opaque) = under + ground

Although the form is built from 'under' + 'ground', the sense 'secret organization' depends on a metaphorical shift to covert activity and is not predictable from the parts.

Etymology

Underground as a noun can mean a secret group because it suggests working under ('below') the ground ('the earth') and therefore out of sight. That's why an 'underground' organization hides its activities while it works against the government.
