Last August a Berlin book launch event was cancelled unexpectedly.
By ‘a Berlin book launch event’ I mean ‘a book launch event that was going to be held in Berlin’. I say it like that just to be concise. Does it convey my meaning? And isn’t there anything wrong about its English? I am asking because there seems to me to be too many words in a row there, and I said maybe it is linguistically incorrect or not clear enough.
Yes and no.
Yes, it is grammatically and logically correct.
No, it is stylistically weak — the word event is superfluous. A launch is an event.
Less is more.
I think the OP meant to write
a book launch
Difficult to know for certain when comments asking for clarification have been deleted and no one can ask the OP directly.
Books are launched, they are not normally eaten for lunch. Moreover, "book lunch" could also refer to making table reservations at a restaurant. Sometimes concision is not an improvement, and I feel this is the case here.
I've never heard of a book lunch to mean a formal meal where people gather to talk about literature or the release of a new book by a well-established author. Neither it seems has Google.
To avoid ambiguity, the OP could rewrite their original sentence as
Last August the event for the book launch in Berlin was cancelled unexpectedly.
No, it really doesn't convey your meaning.
"Book lunch event", what does that even mean? An event where people meet and discuss books over a midday meal? What kind of books will you be discussing? What aspects of the books will you be discussing?
Did you mean launch instead of lunch? An event where you let the public know about newly available books that are just about to be published and sold for the first time? I suspect so, but I'm not sure. There's a pretty big difference between the two.
"Berlin book launch event" would make sense, if that's what you meant.
