Please answer the following question: Extract the answer to the question from the following context. Question: What type of compound is not used in Dutch? Context: Like most Germanic languages, Dutch forms noun compounds, where the first noun modifies the category given by the second (hondenhok = doghouse). Unlike English, where newer compounds or combinations of longer nouns are often written in open form with separating spaces, Dutch (like the other Germanic languages) either uses the closed form without spaces (boomhuis = tree house) or inserts a hyphen (VVD-coryfee = outstanding member of the VVD, a political party). Like German, Dutch allows arbitrarily long compounds, but the longer they get, the less frequent they tend to be.
A:
open form with separating spaces
