Below a few rules are given on how to estimate the grammatical gender

Every rule provides a set of endings, which help identify particular

are genders, and column contents are endings which help identify this
gender.
The rule coveres at least {{selected_rule.rule_coverage}} of all German nouns. On the nouns where it
applies, its accuracy is {{selected_rule.rule_accuracy}}%. {{selected_rule.rule_description}}
