Sui generis
In local government, a "sui generis" entity is one that does not fit with the general scheme of local governance of a country. For example in England, the City of London and the Isles of Scilly are the two "sui generis" localities, as their forms of local government are both (for historical or geographical reasons) very different from those of elsewhere in the country. 
In a press conference during which reporters were trying to analyse his political personality, Huey Long said, "...say that I am "sui generus", and let it go at that."
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.
