Answer 2

Mandarin. As mentioned before, Mandarin is
unanimously considered the toughest
language to master in the world! Spoken by
over a billion people in the world, the language

native languages use the Latin writing system.

languages for English speakers to learn
because English has at least 5,000 loan words
from Old Norse, and shares the same word
order, grammar and syntax as Norwegian.
