I am Greek (born/raised). I understand that for some foreign people it’s hard to go through all Greek Root words like these:
But if you are gonna deal with medicine, pharmacology or a few sciences these roots are gonna be very useful to learn. I recommend the above wiki lists to all people that wanna learn Greek.
The best advice I can give is to attribute 1 specific
‘guide’ word for each root that you know VERY well.
Bateman, about -algia (/άλγος = pain,) actually the most common greek word for pain is: πόνος/ponos. ‘άλγος’ is only used in formal medical circumstances.
Feel free to ask me about how we use each specific word or root in greek (modern or ancient)
