what's the difference between "allein" and "alleine" ?
please, give me kindly some examples.
nothing at all, just sometimes alleine feels better.
Jetzt bin ich allein = Now I am alone
Ich bin immer alleine = I am always alone
Could be said
Jetzt bin ich alleine
Ich bin immer allein
however one just sounds better at the time, but it's not a big deal.
Might "sound" better to some, but still it doesn't make a difference and hasn't anything to do with time (now, always or whatever). You could still say "Jetzt bin ich allein" or "Jetzt bin ich alleine". It really does not make a difference.
BUT: "Allein" is the formal and correct word to use. "Alleine" is rather colloquial and often used by children.
Duden gives: allein, umgangssprachlich auch alleine
I take that to mean: allein is always correct, whereas alleine might not always be.
Alleine in formal text is a bit weird, since it is more colloquial like you said, but on the internet you can never be wrong.
