  10 "AkH. 11. (old orthography)", caused by bad handling of forbidden words
  11 of alias compressed dictionaries during run-time dictionary extension.
  12
  13 Note: accepting also all – previously forbidden – affixed
  14 forms of the modified stem is a removed function: "Grammar by" spell
  15 checking (for example, in LibreOffice via SPELLML interface of Hunspell)
  16 supports user words with affixation and compounding.
  17
  18 The original idea was to add substandard or interfering words
  19 as forbidden words – but with flags – to the dictionary, and adding
  20 the stem to the personal dictionary could “switch on” the affixed
  21 forms of the word, too. Now the suggested method is using
  22 "Grammar by" personal dictionaries, as in LibreOffice:
