Introduction
摘要
16.8 million people (including 6.2 million functional illiterates) in Germany (Grotlüschen et al., 2020) and 1.9 million people in Austria (Kneil et al., 2020) have noticeable problems with reading and writing in German. Non-native German speakers, older people, and persons with low literacy may have a limited vocabulary or know only a few grammatical constructions, so they have problems understanding lexically or syntactically complex sentences (Bredel and Maaß, 2016; Saggion, 2017).
