Prepositions and their relation to semantics have always been questionable. They are often considered to have too little semantic content or, vice versa. When it comes to prepositions, the question that may arise refers to whether they should be regarded as lexical elements with their own lexical and even metaphorical meaning, or rather as semantically empty grammatical elements. Therefore, this article aims to contribute to a better understanding of the semantics of prepositions, since they often have a range of meanings and can be used to describe various relations depending on context. Meaning ultimately derives from the complex interaction between real-world experience and conceptual processes which create and organize this experience in meaningful ways. Focus will be laid on the primary meanings of prepositions, e.g. the spatial uses and on their relations to the metaphorized ones because the metaphorical uses can really be a great challenge. I consider prepositions to be one of the most difficult grammar areas due to their polysemous nature. The idea is shared that metaphorical uses of prepositions are those which are used primarily to denote space and then extend their meanings to other functions such as manner, means, etc. The present article aims at studying the different meanings expressed by some prepositions in order to explore the conceptual polysemy of prepositions. These different meanings are thought to be metaphorical since they are related to the original spatial meaning. The conclusion can be drawn that this relation between the meanings is a case of polysemy. [ABSTRACT FROM AUTHOR]
