The article gives a linguistic analysis of place-names ending in -awka and -awki. The purpose of the paper was to single out oikonyms whose endings are also suffixes which form names and to analyze the role they play in those names. Place-names ending in –awka are very rare. Their basis are verbs, but also adjectives and nouns. They bring topographic and sometimes cultural information. It is typical that (apart from the oldest documented name of the village of Rudawka in Western Pomerania (Pomorze Zachodnie) there are no such names in the western zone, they occasionally occur in Western Pomerania and central Poland. There are more such names in Lesser Poland (Małopolska) and in the eastern part of Poland. All this proves that the -awka suffix does not perform a word- forming function.
