By now we have covered nouns, adjectives, pronouns, verbs, gerunds, and participles — all of which vary their endings. What is left are particles, those words, usually short, that do not inflect, that have one unvarying form. They are equivalent to English prepositions, conjunctions, nonderived adverbs, and interjections.
Prepositions serve to relate noun phrases to the rest of the sentence. As such they function like the cases, and supplement them, expressing relations that the limited number of cases cannot. For the most part, they must only be used in association with particular noun cases; those that can occur in different environments may change meanings when used with different cases. In particular, prepositions that refer strictly to position with the locative indicate direction of motion when used with the accusative or genitive.
