My current research concerns the style history of the non clause formed sentences, or rather that subcategory thereof that the Swedish Academy Grammar (SAG) calls main clause equivalents. These latter are not at all stylistically uniform, as they consist of everything from specifically written language types as head lines and sign texts to specifically spoken language types as Sw. tyst (med dig) 'shut up'. Apart from the former types there might by a notion of these main clause equivalents being a rather young phenomenon in written language as part of a modern "uprise" against the norm of complete main clauses. One might therefore expect that these main clause equivalents became more and more rare as the written language of the oldest times became more and more standardised. Yet, there is also reason to believe that at least some types have had there functional place in written language of all times, however standardised it was, although perhaps different types in different genres (or at different times).
