My German teacher says that both of the above phrases are correct. However, based on what we have learned thus far, since "welch" is a 'der word', it takes a "-er" ending in the nominative case. Since "klug" is an adjective following a 'der word', it must take a "-e" ending in this case.
There are a few things I don't understand in this sentence.
Are both versions correct? Why or why not?
If so, is this a special case, or is there a general rule for when this is permissible? (The endings act as if "welch" is an 'ein word' in the second sentence.)
This one's not as important, but since "welch" translates to "which", why is this sentence an exclamation(What a smart man!), rather than a question (Which smart man?). How would I ask "Which smart man?"
Thanks in advance for your help!
