I haven't seen it called strong endings before (I just read the part in the link you're talking about). The term I'm familiar with for indefinite articles is "mixed endings" or mixed inflection/declension. This wiki article shows the endings for strong inflection (when there is no article), weak inflection (definite articles like der), and mixed inflection (indefinite articles like ein):
Hope that helps. If not, ask again.
Anything after a verb is accusative. Ask yourself after the verb "Wearing what". 'A white shirt' is accusative. And then because it follows 'ein' (indefinite article) its mixed inflection. and then look at the gender of the noun in front (neuter) ...So... Mixed inflection, accusative neuter (ends with es) http://en.wikipedia.org/wiki/German_adjectives#Mixed_inflection
Is this a "Maedchenhemd" ?? http://t2.gstatic.com/images?q=tbn:ANd9GcS8DhLHiXQ9kFj3u87oRf4ZPCfPbhyHBR6Hm4zvUCOl_jDNzTxk
I learned a shirt for a girl is a shirt in the meaning and cut of a blouse which is in German a "Hemdbluse" and for the boys a "Oberhemd". Or you mean the style of shirt business women wearing, they look very similar to men's shirts with the opposite button order.
Just being curious. (hope its not too far off topic)
I mean business style shirts with, as you say, the buttons on the opposite side. Not that they are only worn by business women. I opted out of the corporate world years ago but I still have shirts I wear when I need to look smart. I'd describe the photo in the link as a blouse.
shirt = Hemd, Oberhemd (male),
T-shirt = T-shirt (unisex),
Bluse/Hemdbluse = blouse (fem),
and now I learned: shirt = shirt (fem) in the meaning of business style shirt for girls is also fine.
Well, thanks for that helen. Quoting: "...have shirts I wear when I need to look smart." I like that idea, -you made my day! :-)
Ok, here I go again. Sie tragt ein weisses Hemd (don't have the ") She is wearing a white shirt. When I mouse over the tragt, it gives me 3 possible answers earn, register, and check. None of them are anywhere near what they accepted as correct. If the mouse over suggestions are suppose to be correct why is wear not there. Because of the possible answers I put She earned a white shirt. Why wouldn't that be acceptable.
Never mind. I found a good explanation here: http://german.about.com/library/weekly/aa030298.htm
so "Das gelbe Kleid, Die gelbe Kleidung, Der gelbe Hut" and "Ein gelbes Kleid. Eine gelbe Kleidung. Ein gelber Hut" am i right?
