hellos = [
    "Hello",
    "Tungjatjeta",
    "Grüßgott",
    "Вiтаю",
    "dobrý den",
    "hyvää päivää",
    "你好",
    "早上好"
]
for hello in hellos:
    print(hello + 'World')

Your code currently returns 'HelloWorld', 'TungjatjetaWorld', ect..

So all you need to do is simply add a space in the string

hellos = [
    "Hello",
    "Tungjatjeta",
    "Grüßgott",
    "Вiтаю",
    "dobrý den",
    "hyvää päivää",
    "你好",
    "早上好"
]
for hello in hellos:
    print(hello + ' World')

You want to add the same word to each item in the list? Then something like this:

for i in range(len(hellos)):
    hellos[i] += " another_word"
