So I have come across this sentence while doing some German practice:
Obwohl sie jünger als ich ist, ist meine Schwester sehr unternehmungslustig.
I have a couple of questions that I would appreciate some help with:
Why is 'ich' used rather than mich? I would of thought that the sister is in the nominative case and me is in the accusative, which would lead to using mich?
What causes the ist in the second part of the sentence to come before 'meine Schwester' and not directly after it, isn't the verb supposed to be the second idea of the sentence?
Thanks for any help guys.
