Based on data elicited from Czech Ten Ten 2017 corpus, this paper puts
forward an analysis of the semantics of Czech verbal prefix pro-, formulated
within the framework of degree semantics. Prefixes are analyzed as degree
modifiers. The paper demonstrates how this analysis captures the properties
of pro-, one of the most complex and challenging verbal prefixes in Czech. It
is proposed that spatial, temporal, terminative as well as idiomatic uses of this
prefix can all be unified under a scalar approach. The distinctions observed
between these uses are restricted to the types of scale and comparative
standard that are involved in the semantics of the verbal phrase. Special
emphasis is placed on the role of the scalar properties of the nominal
arguments in the composition of change of state predicates.
