Well , Ive been learning english for a while now , and Im about to finish my studies , so now I want to learn an other languaje but I dont know wich should I pcik , Im between russian , dutch , german and french , dont miss understand me , I want to learn all of them eventually , Ive been tring to learn a bit of every one by using apps and pages like duolingo but Im not used to learn an idiom word by word , so I will probably take a course , so I was hopping while I ask for opinion for which its the most interesting , practise a bit of writting in english because Im quite bad at it
