Editing Vowel harmony (section)

=====Agglutination vowel constraints=====
Hungarian language is a consonant oriented language that makes vowel harmony possible, but the vowels in agglutinations can not be changed according to free will. Some of such vowels even change the meaning of the word
* For this reason the vowels in agglutinations are constrained seemingly arbitrary
For example it was [[Vowel harmony#Vowel cleft lipness|mentioned]] that the last cleft lip vowel in the root of the word induces an agglutination with also at least one cleft lip vowel in it, however this is not always the case due to certain agglutinations are constrained. One good example is the {{lang|hu|-k'''o'''r}} agglutination that can not take any other vowel, but '''o'''
* {{lang|hu|<u>ö</u>t<u>ö</u>t}} - in accusative case the vowel before '''t''' is '''not as''' constrained
* {{lang|hu|<u>ö</u>tk<u>o</u>r}} - in this case {{lang|hu|o}} vowel is constrained not to be cleft lip
* {{lang|hu|<u>e</u>gyk<u>o</u>r}} - in this case {{lang|hu|o}} vowel is constrained not to be frontal (high), and not to be cleft lip
There are further examples of vowel constraints in agglutinations not only for cleft lip-ness with some agglutination possessing
# only one ({{lang|hu|-k'''o'''r}}, etc...)
# only two ({{lang|hu|-z'''ó'''}} - {{lang|hu|-z'''ő'''}}, {{lang|hu|-'''á'''s}} - {{lang|hu|-'''é'''s}}, {{lang|hu|-v'''a'''l}} - {{lang|hu|-v'''e'''l}}, etc...)
# only three ({{lang|hu|-h'''e'''z}} - {{lang|hu|-h'''ö'''z}} - {{lang|hu|-h'''o'''z}})
# or more forms (accusative case, etc..)
The vowel in these forms are only short, or only long
* Generally speaking an agglutination with a given meaning - or even a given context of meaning'''s''' - may only possess either a long, or a short vowel through out its forms regarding constraints
In the following examples the used vowels in the agglutinations change the meaning
# {{lang|hu|tévé}} + '''zk''' = {{lang|hu|tévéz<u>e</u>k}} - <u>i</u> am watching tv
# {{lang|hu|tévé}} + '''zk''' = {{lang|hu|tévéz<u>i</u>k}} - <u>he</u> is watching tv
# {{lang|hu|tévé}} + '''zk''' = {{lang|hu|tévéz<u>ő</u>k}} - <u>people who are</u> watching tv
As you can see in the last example's agglutination of {{lang|hu|tévé'''z<u>ő</u>k'''}} is with '''long''' vowel. This resulted in a '''noun''', not a '''verb'''. The '''long''' vowel renders meaning completely detached of the other two examples' context. The other two are in a context with only '''short''' vowels, with the rest of their context is the following:
# {{lang|hu|tévé}} + '''zl''' = {{lang|hu|tévéz<u>e</u>l}} - <u>you (singular)</u> are watching tv
#* Agglutination {{lang|hu|-z'''e'''l}} is with '''short''' vowel
# {{lang|hu|tévé}} + '''ztk''' = {{lang|hu|tévézt<u>e</u>k}} - <u>you (plural)</u> are watching tv
#* Agglutination {{lang|hu|-zt'''e'''k}} is with '''short''' vowel
# {{lang|hu|tévé}} + '''znk''' = {{lang|hu|tévéz<u>ü</u>nk}} - <u>we</u> are watching tv
#* Agglutination {{lang|hu|-z'''ü'''nk}} is with '''short''' vowel
# {{lang|hu|tévé}} + '''znk''' = {{lang|hu|tévézn<u>e</u>k}} - <u>they</u> are watching tv
#* Agglutination {{lang|hu|-zn'''e'''k}} is with '''short''' vowel
Likewise using the same agglutination used to {{lang|hu|tévé'''z<u>ő</u>k'''}}, the word {{lang|hu|uta'''z<u>ó</u>k'''}} is also with '''long''' vowel, that is also a '''noun''' against {{lang|hu|uta'''z<u>o</u>k'''}} with a '''short''' vowel that is likewise a '''verb'''
