The complexity of the phenomena associated with the course of the cognitive processes that determine an efficient learning, excludes the possibility of collecting knowledge in other ways than neuronal-information. It excludes also possibilities of interpreting it, in other ways than with use of respectively formalized cognitive models. The presented paper is a kind of summary of the latest achievements in this field.
This paper addresses the issue of the historical development of for fear (that) in English – a prepositional subordinator ushering in fi nite clauses of purpose in which negation is inherently coded, i.e. the content of the subordinate clause is negated by the complementiser which does not contain a negative particle in itself. The rise of this construction is studied within the theory of grammaticalization and it turns out to be a regular case of grammaticalization following the mechanisms of grammaticalization such as desemanticisation, extension and decategorialisation.
