Clearly, the universe - I mean, der Universum - was trying to tell me something today, as in quick succession I came across four fantastic German loanwords, two of which I knew and two of which I didn't:
weltanschauung - "worldview" (used on Laura Valaas' blog)
gemütlichkeit - "cordiality, warm friendliness" (Worthless Word of the Day for May 7, 2007)
sprachgefuhl - "an intuitive sense of what is linguistically appropriate" (Merriam-Webster Word of the Day for May 6, 2007)
der das-letzte-Wort-Haber - "last-word-haver" (this might be a nonce word, but it was used in a student column in the Carletonian, Carleton's campus newspaper. and I like it)
Ich hasse der das-letzte-Wort-Habers. Or something.
