This paper observes the Swedish auxiliary verb 'h?lla p?', commonly used as a progressivity marker in pseudocoordination with a process verb. In some contexts, especially in combination with negation, 'h?lla p?' gives the process denoted by the lexical verb a flavour of constancy.
The corpus evidence proves that this semantic feature is spreading onto non-negated contexts, too, which implies that the auxiliary construction 'h?lla p? och' is becoming polysemous. This interesting semantic shift is related to Hopper's (1987) idea of grammaticalization regarded as 'movement towards structure' as well as to the concept of 'context-induced reinterpretation' as one type of semantic shifting described by Heine, Claudi and Hünnemeyer (1991).
