Deutsch "werden", "bleiben" : schwedisch "bli", "jörbli" ; viele Daten, einige Beobachtungen, ein oder zwei Ideen, noch keine überzeugende Lösung
- In contradistinction to main verbs copula verbs like 'sein', 'werden' or 'bleiben' ('be', 'become' or 'remain') can, though with some restrictions, take projections of all lexical categories as complements. Semantically 'werden' and 'bleiben' are considered to be dual operators, related to each other by inner and outer (= dual) negation. But there are contexts where 'bleiben' seems to assume the meaning of its dual 'werden'. What at first glance appears to be an idiosyncracy of German turns out to hold for Swedish, Brazil-Portuguese and other unrelated languages as well.
'Werden' is more restricted than 'sein' and 'bleiben', it cannot have a locative complement. 'Bleiben' has the widest distribution, it can also take infinitives of verbs of position as complement. But in this case 'stehen bleiben' is ambiguous between a "remain" -reading and a "become" -reading.
In 15th century the Swedish verb 'bliva' - a borrowing from German - has undergone a change from the "remain"-reading to the "become"-reading. The "become"-reading of 'bliva' (later form 'bli') is only blocked (as is the German verb 'werden') in the case of a locative complement, where the "remain"-reading has survived. The two readings of 'bli' do not produce any ambiguity, except when taking a verb of position as complement - much the same as in German.
The paper attempts to pinpoint the conditions that lead to this surprising shift of meaning between duals.
