The analysis makes use of two comparative concepts of subjecthood; argumental subjecthood, centred on the argument-structural characteristics of subjects, and informational subjecthood, which corresponds to the syntacticization of information-structural properties. Subjecthood is defined as a labile multi-level configuration of argumental and informational parameters. This approach sheds new light on notorious tricks of Germanic syntax such as oblique subjects, expletives, scrambling and subjectless passives.
