Sui generis
A similar case that led to the use of the label "sui generis" is the relationship of New Caledonia relative to France, because the legal status of New Caledonia can aptly be said to lie somewhere between a French overseas collectivity and a sovereign nation. Although other examples of such status for other dependent or disputed territories may exist, this arrangement is unique within the French realm.
Swedes (Germanic tribe)
Most scholars agree that "Suiones" and the attested Germanic forms of the name derive from the same Proto-Indo-European reflexive pronominal root, , as the Latin "suus". The word must have meant "one's own (tribesmen)". In modern Scandinavian, the same root appears in words such as "svåger" (brother-in-law) and "svägerska" (sister-in-law). The same root and original meaning is found in the ethnonym of the Germanic tribe Suebi, preserved to this day in the name "Schwaben" (Swabia). The details of the phonetic development vary between different proposals.
