another grammar question

Hi! well I have more questions... Here in "Ich fühle mich nicht wohl. Mir ist übel und schwindelig"... why after "Mir" is used "ist" instead of "bin" if we are talking about "me" (mir). In the sentence "Ja, er müsste noch in der Tüte sein. " why the verb "müssen" is in this case müsste and not just musste (in past tense) or muss for er (or maybe is another verb?) I know Paul will answer me so... Thank you Paul in advance and for answering all my past questions!!!! :)

Hello again Cat O, It's always "ich bin" never "mir bin". "Mir ist übel und schwindelig" is modern German for: "Es ist mir übel und schwindelig". If you say "ich bin übel" the meaning changes to "I am nasty" or I am bad in doing something depending on in which context you use it. Other examples: "Mir ist langweilig" is "I am bored". "Ich bin langweilig" is "I am boring". The adjectives (müde, froh, gesund, traurig, hungrig, ruhig) are used with "ich bin...". The adjectives (kalt, heiss, warm) are used with "Mir ist..." To mix up "ich bin" and "mir ist" is a quite common mistake done by German students. I don't think you will get missunderstood. "Ja, der müsste noch in der Tüte sein". "Müsste" is here "it should be still in the plastic bag". Examples for müsste: "Ich müsste mal zum Zahnarzt" is "I should go to the dentist". "Da müsste noch Wein im Kühlschrank sein" is "There should still be vine in the fridge". "Musste" means here "should have" If you use "musste" you leave out "noch". "Der musste in der Tüte sein". It was necessary to put it in the plastic bag. It should have been in the plastic bag some time in the past but doesn't matter if it's there still. I hope this helps! Viele Grüsse Paul
