Morphology

heliocentricity = heliocentric (transparent) = helio + centric + ity

Formed by adding the noun-forming suffix '-ity' to the adjective 'heliocentric', yielding the state or quality of being heliocentric.

Etymology

The word heliocentricity comes from the Greek word helios meaning 'sun' and the part -centric meaning 'centered', the same idea as the common word center. So, heliocentricity simply means 'sun-centered', which is why it names the idea that the Sun is at the center of the solar system.
