Greek words “agricola” (a farmer) or “nauta” (a sailor)

Greek words? Methinks, dear Homer, you have nodded.

These two (unlike “sophia”) are found in Latin as well, but they are both Greek imports, as far as I remember from school. Greek “agros” (field, farm) is the root word for “agricola.” The Greek origin of “nauta” is easier to proof for this discussion’s sake -- e.g. when one dissects the word “cosmonaut” meaning in Greek “space-(universe)-sailor” one gets a purely Greek word “cosmos” and another Greek word “nauta” -- the latter borrowed by Latin.
I am going to double-check in some clever book later, but I’m 98.675% certain it is correct. Cheers!
