In scientific terms you always see those words like φῶς, "light", and σύνθεσις, synthesis, "putting together". This seems like to my mind Light=Noun and Putting together= verb. Hence my hypothesis about Noun + Verb being pretty standard in the Scientific world. Not sure where this comes from but almost every term of Ancient Greek origin seems to follow this path.
Photograph is another, light + drawing follows this pattern. A third that springs to my mind is Pathognomonic from the Greek πάθος + γνώμων.
