This article presents the results of a corpus study of clausal postpositioning, that is, the occurrence of a sentential constituent in the postfield of the matrix clause to which it is syntactically linked, in German regional language. Analysis of 11,027 clauses from 60 spoken regiolect and dialect texts reveals that clausal postpositionings occur most frequently as non-relative finite clauses, followed by relative clauses, and lastly, infinitival constructions. Notably, while non-relative finite clauses comprise a smaller proportion of postpositionings in regiolect compared to dialect, relative clauses and infinitival constructions show the opposite trend. Adjunct clauses occur most frequently, followed by complement clauses, in both regiolect and dialect. Furthermore, in both varieties, postpositioning is more prevalent in verb-first and verb-second clauses than in verb-final clauses. This finding is attributed to restrictions on syntactic subordination. Finally, non-relative finite clause and relative clause types that may be embedded in both the postfield and inner field are center-embedded at mean relative frequencies of 13.42% and 28.17%, respectively. These findings shed light on contradictory claims in the literature regarding the possibility and frequency of clausal embedding in the inner field.
