Nouns ending in -erei in German generally fall into one of two categories.

banner3 PLACEHOLDER

First, it can be noted that this suffix has a connection to the French suffix -erie, which comes from the Latin -aria. Both -erei and -erie often appear in words for shops and workshops, like la boulangerie and die Bäckerei (the bakery). 

Ja, wir gehen auch immer in die Bücherei. Nicht wahr?

Yes, we're always going to the library. Isn't that right?

But not every noun ending with -erei denotes a physical place. More broadly, the suffix forms nouns referring to activities, trades, or practices, often derived from verbs. A good example is the word die Fischerei, which can be a place where fish are caught and sold, or simply refer to the industry or activity of fishing, as in this sentence:

Die damit einhergehende Ausbeutung des Meeres durch den Menschen in Form von Fischerei ...

The associated exploitation of the sea by humans in the form of fishing...

Sometimes the -erei ending gives a word a more negative or dismissive connotation, especially when referring to repeated or excessive behavior. For example, das Kleckern is a neutral word for spilling, but die Kleckerei suggests a messy or annoying situation:

Dann wird Kleckerei zur Schweinerei .

Then a spill becomes a mess.
