U why do you think the word solar is derived from the root word "only? "sol. alone, only. latin

Hi! 'Sol' doesn't actually mean alone, lonely, it does in fact mean sun! Solar -> relating to or determined by the sun so it kinda makes sense. If you're looking for the latin word for alone, lonely, you're looking for 'solus'. I hope i was able to help!

What are you trying to analize

Doulingo is good. you can also watch movies that are in french, i am using this tactic  for japanese  and it a lot. listing to music with  french  lyrics would work well too because  you could absorb  the words while having fun.hope this ! : )
