This is very interesting
If u are interested in what the root words mean in Greek I can help with that.
In most of these words the 2nd part is -logy and it comes from the greek word λόγος (logos) meaning speach.
So for example psychology comes from the words ψυχή (psychi) that means soul and λόγος that means speach and as a whole it means the science that talks about the soul
I will type the root words written in greek, then in the brackets how they sound in Greek, their meaning and then the meaning of the whole word
- geography : γή (gi) = earth + γραφή (grafi) = text = writing about the earth
- anthropology : άνθρωπος (anthropos) = human + λόγος = talking about humans

- neurology : νεύρο (nevro) = nerve cell = talking about nerves
- philology : φιλος (filos) = friend = friend of the speach
- cosmology : κόσμος (cosmos) = world = talking about the world (world in greek has a general meaning not just earth)
- geology : (same word as geography) = talking about earth
- dermatology : δέρμα (derma) = skin = talking about the skin
- ethnology : έθνος (ethnos) = people of a specific country = talking about people of a specific country
