What about hygroscopic cloud seeding, which works by spraying clouds with particles that absorb water to make the clouds rain off?

Examples

  • Brake fluid is hygroscopic (well, dot 5 apparently is not), which means that after a while, the boiling point is lowered.

Morphology

hygroscopic = hygroscope (opaque) = hygro + scop + ic

The components are Greek combining forms unfamiliar as standalone English morphemes, so learners cannot reliably infer the meaning from the immediate base form.

Etymology

Hygroscopic comes from two old parts: hygro- meaning 'moist' or 'wet' and -scopic (like scope) meaning 'to look' or 'show'. A helpful image is a 'moisture watcher' that pulls water from the air, which is why hygroscopic describes a material that tends to absorb moisture.
