One example is Rose which in other parts of the world and languages become Rose, Ross, Rossi, Ruus, Ruuska.
While we know, Rose is a flower, it is possible that the early nomads/travelling people identified themselves with flower, animals, plants, etc.
In Indo European langauges adding suffixes and prefixes to give meaning to a word is a known fact. Example in case of Rose can be Ruus+Ka, which could mean people from the Rose clan. Root word being Rose, i.e. name of the flower.
