Surface Forms
Morphology
heliostat = helio + stat
Formed from Greek combining elements helio- ('sun') and -stat ('standing/device'), which are not productive standalone words for average B1 learners, so the meaning is not directly derivable from familiar English bases.
Etymology
Heliostat comes from the Greek helios ('sun') and -stat ('to stand' or 'stay in place'), like in thermostat. So a heliostat is a device that 'stands' the sun in one direction by moving a mirror to keep sunlight steady where you want it.
