What the study found
The authors argue that viewpoint, or perspective, is central to the meaning of modality, a semantic domain concerned with speakers' attitudes toward a proposition. Using German sollen ('shall') plus infinitive as an example, they propose a unified analysis that connects root, epistemic, and evidential readings.
Why the authors say this matters
The authors conclude that their analysis helps explain how different meanings of modal verbs shift over time and how modal verbs relate to the imperative. They say this sheds light on basic processes of perspectivization in modal verbs and on their role in linguistic theory.
What the researchers tested
The paper combines earlier formal semantic and functional cognitive approaches into one analysis of perspectival mechanisms. It uses historical empirical evidence to study German modal verbs, especially sollen plus infinitive.
What worked and what didn't
The proposed viewpoint constellation is presented as able to unify root, epistemic, and evidential readings of German modal verbs. The authors also say it can describe semantic development and explain the complementary distribution with the imperative.
What to keep in mind
The abstract focuses on German sollen plus infinitive, so the claims are exemplified through that verb rather than shown here for all modal verbs. The abstract does not describe specific limitations beyond the scope of the analysis presented.
- The paper treats viewpoint as central to the meaning of modality.
- German sollen ('shall') plus infinitive is used as the main example.
- A unified analysis is proposed for root, epistemic, and evidential readings.
- Historical empirical evidence is used to support the analysis.
- The authors say the analysis also explains the link to the imperative.
