Post-creole continuum#Stratification

As acrolect the Strataforschung denotes the winner of the most prestigious form of a language that is mostly identical to the standard - or high-level language.

The term derives from the Greek akron ἄκρον "top" and Greek λέγω Lego " speak / say " from. It was introduced in 1965 by William Stewart as opposed to basilect and recorded in the early 1970s by Derek Bickerton to the phenomenon of code-switching, ie the abrupt change between a creole and a standard language - in this case the English - to describe. As an intermediate between acrolect and basilect Bickerton also conducted the notion Mesolekt.
