Castle or lock, correct, but also closed as in "er schloss die Tür = he closed the door". In which case it would not be capitalized.

...or in other words, because "schloss" is not a noun, it's a verb.

danke, ich habe vergessen, dass schloss auch ein Verb ist.

Good one, kyle. You really had us all going there for a while, thinking you were a real person who had a clue. (-: Nice to wrap it up, though, on a Friday.






Just in case you are, all appearances to the contrary, in fact interested in learning German,

http://wortschatz.uni-leipzig.de/

has a large text corpus and generally manages to distinguish nouns (always capitalized) from verbs (usually not). I would imagine that they use a certain amount of hand markup, not just pure mechanical analysis.

Did you do any sort of post-processing to these texts before you created these lists, kyle? From the looks of it, you need to look into a solid German part of speech tagger.

OT: Kyle, why do you have "I" and "German" in #0? I thought you didn't believe in capitals in English...;-)

dass schloss auch ein Verb ist

No, that's not quite right, kyle. "schloss"[sic] is always a verb.
By the way, in older German texts the noun was spelled "Schloß". That might also affect your programming...

@KinkyAfro: I'm not so sure your comment is OT. Kyle's failure to "embrace" capitalization is the source of his confusion. Anyway, this thread is a marvelous example of poetic justice. It answers kyle's question above pretty well.

By the way,
auch das Verb wurde nach alter Rechtschreibung mit ß geschrieben.
