Although it's not a formally recognised dutch word, it is an example how we can connect words into monstrous lengths. But if you want to write it down in English, here's what you get:

Greyhound collar key hole maker trade school association holiday fee collectors cottage

[MYE2001]

Muvaffakiyetsizleştiricileştiriveremeyebileceklerimizdenmişsinizcesine
As if you would be from those we can not easily/quickly make a maker of unsuccessful ones

But anyone uses this in daily speech,it is strange.Word below is also long and understandable.Not like previous.

Çekoslovakyalılaştıramadıklarımızdanmışsınız
It is said that you are one of those people whom we could not turn into a Czechoslovakian?

Ofcourse, the longest you could make is this:

Ofcourse, the longest you could make is this:
lapselapselapselapselapselapselapselapselapselapselapselapselapselapselapselapsed - grand-grand-grand-grand(alot of grand)children

This same method of creating a long word works in Finnish as well:
lapsenlapsenlapsenlapsenlapsenlapsenlapsenlapsi

[MandelSoft]

Works in dutch too:

achterachterachterachterachterachterachterkleinkinderen

In slovenian it would be like this:
