"How do you say __" or "What is the meaning of __"
If I were to ask a native speaker in France about a word they said, how could I ask them what the meaning is.
Also, how would I ask how to say a particular work in french (most likely saying the word in english)
Merci beaucoup!

Question

Answer

okay so first you have to say something like that : Que signifie "X"? or que veut dire "X"
Then If you want a translation you should  say : Comment dis-tu "X" en anglais ? / Comment dis-tu ce mot en français ? 
later

Answer

Pourrais-tu m'expliquer (le mot/ce qu'est une) [...]
Comment dis-tu (word in english) en français?
