Think of it as "having wine to lunch"; where we might say we're having something at lunch or with lunch, the Germans say "to". Prepositions never translate well between languages, you just have to expect it and learn the differences.

I find it easiest to think of the word meaning the same thing, but being used differently.

Prepositions are like that in all languages, even (especially) English

Just make note cards, it really works!!! :)

I guess this is how German grammar works.. The proposition in German is really confusing and the only way to learn them is to memorise them and memorise which verb goes with which proposition. I'd suggest a book called Deutsch als Fremdsprache (Uebungsgrammatik fuer die Mittelstuf) Niveau C1. There is big list of verbs with propositions that I had to memorise while studying german for the DSH exam which is really useful and you really need to know while speaking German. If you use the wrong proposition I think the whole meaning will be confusing for the one you are speaking with.

Assuming that's what you wrote, the problem is probably just the future tense. It makes sense, but this phrase was written in the present. "Most likely" shouldn't be a problem.

wahrscheinlich = probably

anscheinend = seemingly

vielleicht = perhaps

The most interesting of these is "anscheinend".

It means you have some some reasons to believe things are like that, only you are not quite sure yet.

"There was a clinking of glasses. Anscheinend gibt es Wein zum Essen." (It seems there will be wine for lunch)

Because it's a really awkward translation, and in German, "gibt" is used much more loosely than "gives" is in English.

"Es gibt/gibt es" is really better translated as "there is" or "there are."

'gibt es' is a common phrase that most often translates to "there is" rather than 'it gives.' Don't ask me why. That's just what I was taught.

"To the lunch" is not proper english, however, "at lunch" would be acceptable as well as "with lunch".

"Gibt es" and also "es gibt" mean "there is".
