So in my Opinion a guy that speak portugues , german, spanish and english...
German is a harder language then english because like DEN said you have the
"der ,die ,das" tought comparing to other languages like russian or polish for me looks like hell
My Tip is dont try to connect any language to your home or know language as i speak multi languages that helped me alot
but final word is learn german isnt that hard if you rly wanna learn it i did it also and it wasnt that hard
Peace DioZ
