The following prepositions and inseparable prefixes are added to latin verbs. Some intensify and some change the meaning of the latin verb. This list may be particularly helpful if you are trying to learn a long list of vocabulary words, as I once did, in preparation for the SATs or PSATs. By really knowing these parts you may be able to rule out some of the choices on multiple guess exams.
