Groups
======

 * Separated by <|>; contain units, separated by <;>.
 * Contained units related by sharing the same translation.
   * Usually synonyms.
     * It is assumed that they always are.
     * Debatable: differently gendered forms
       . Ex.: "Bäcker {m}; Bäckerin {f}"
   . Exception: "nicht können; kann nicht"
   . Exception: "wir waren; wir waren nicht"
     ? TODO: Catch (suffix "nicht" / "not")?
       - TODO: Investigate further.
       ? Is this special to inflected forms / and/or phrases?
         - Note also the mapped order on the RHS.
     . Same for "tun". (that's all)
     . For "sollen", "dürfen", "haben", "möchten" separated by <|>.
     * Do not confuse with other usages of "nicht".
       . Ex.: "übersieht; überliest; beachtet nicht"
 * Groups may be empty.
 . Obsolete documentation [0] (translated from German):
   "Several translations: similar words / word groups separated by semicolon"
