Describe the bug I added the term Stukturoptimierer to the german dictionary (checked). Then I used "Entwicklung eines Strukturoptimierers", i.e. a declination of Strukturoptimierer. This is not recognized and a warning is issued.

Steps to reproduce Steps to reproduce the behavior:

1. add he term Stukturoptimierer to the german dictionary
2. create a latex file with the text "Entwicklung eines Strukturoptimierers"
3. activate ltex
4. See error

Expected behavior I expected that no warning is issued as my text is correct.
