Italian is pretty easy to learn (at least to me). Many words have it’s root in latin, it is very melodic language.
Russian is also very easy but that’s because I am Slav.
Italian is
very easy to pick up, if you already know French and Spanish, which I do (at least to some extent). If I take a step back, relax, and use my imagination a little, I can basically figure out simple Italian texts such as those on websites and newspaper articles. It is not a terribly complicated language. Portuguese is a little tougher, and Romanian, I can only figure out individual words.
I can “hack my way through” basic Russian, especially if verbs aren’t a major factor, in that I have a small amount of fluency in basic, conversational Polish. I do confess that I still have to run the Cyrillic alphabet through a kind of letter-by-letter mental filter — “I see Cyrillic, but I have to visualize it in Latin”.
I have no expertise in Asian or Semitic languages, though I do find it fascinating that Sanskrit has some primitive roots from which Slavic, Germanic, and Romance languages take portions of their vocabulary. Totally random observation, I found it interesting that the Konkani (former Portuguese Goa state of India) word for “thank you”,
ievkar, superficially resembles the Greek root for thanksgiving — think
“ievkar - Eucharist”, and you’ll see what I mean. It’s pronounced “yev-kar”.
