Swedish
In Swedish, research has reached general consensus in that finite clauses in this language must have an overt subject present. This phenomenon is referred to as the subject requirement. When a clause has no subject present, the expletive subject det 'it' is used. However, under certain conditions, there are clauses in which 'det' is not omitted.

The use of expletive subjects in Swedish is a recent development. In a research by Varho, results revealed that almost all sentences analyzed from Early Old Swedish lacked an expletive pronoun. In the Late Old Swedish, the use of expletive pronouns increased, mostly seen in religious texts, although it was still relatively uncommon. Today, the use of overt expletive pronouns continue to increase with several types of clauses in which expletives appear in.
