The preposition 'over' has long been studied by linguists since it has some semantic features which pose lots of problems for contemporary theories of polysemy and solving those problems might help realize how semantic networks are organized in the mind of a language speaker. Having studied most influential studies on the subject matter, we came up with our own experiment design. We found one specific sense of 'over', namely its covering sense, of a particular interest as in most studies it hasn't yet deserved much attention and its semantic peculiarities have not been properly explained. We designed a survey which aims to specify those peculiarities and now we need to find some English speakers who, by taking part in the survey, could help us collect the necessary data for further analysis.
