First of all, I’d like to say hello to all of You. That’s my first post on this forum.
I’m an archaeologist by education (my specialization is zooarchaeology), classical greek is my hobby and I learn it on my own. I use Schliemann’s method, so I’m interested mostly in search for analogies between greek, protoindoeuropean and modern languages vocabulary (I also collect various dictionaries).
Recently I was thinking about greek word formation. I wanted to create a word “to look like trumpet”, “trumpet shaped” or “horn shaped” using greek σάλπιγξ and εἴδωλον. Because I know the word δρακοντοειδῶς “snake shaped” (Strabo), per analogiam I created word σαλπιγγειδῶσ. Is it correct? What are the rules of putting accents in word formation?
