I swear, that woulda brought down the house in 2003!
The book, that arrived last night, says ‘der Rock’ (¨-e) is ‘skirt’.
That is correct. That’s the most common modern meaning.
I had that book, too!
Ich ube Geige! (can’t remember how to do umlauts on the 'puter). We used to crack jokes about Peter being “im Boot” mit Monika…
And remember the Der Spiegel films? Ah, German class. 
Im Boot.
Du siehst lustig aus, du mit deine Sonnenbrille.
ü is Option+u, u. (Option+u puts an umlaut over any vowel.)
On a PC it’s ALT+252.
Or you can just type oe.
I think everyone made the Peter/Monica joke. ‘Wo ist Monika?’ ‘Im Boot mit Peter!’ 
.
‘deiner’. 
Oh – Just to bring this back to the OP, now that I have the book, the glossary lists ‘to clean’ for ‘putzen’.
This is German’s foremost publisher of German orthography:
Here “Duden” is used as a proper noun, not slang terminology for “young men”.
(As in “All the young duden, carry the 'luden”) 
Q
Named after this dude.
