How to use I am and I'm properly?

Question

an example?

Answer 1

I'm is used in informal conversation and I am is when your a bit annoyed and making a point or being formal. :P

Answer 2

I'm is a perfectly acceptable contraction of I am.  You can use I'm in most casual speech situations, such as with friends.  However, more formal settings (such as school) and most written situations would require I am.

Answer 3

     Both "I'm" and "I am" mean the same thing.  "I'm" IS "I am", but shortened for the ease of speaking.  "I'm" is used almost always in "I am"'s stead in dialouge.  In casual, and even more formal speaking one would use "I'm". ("I'm in a very good mood today." or "I think I'm going to read a book this afternoon.")  

     "I am" is common in (non-dialouge) writing, and when answering a question that uses only "I am".  (ex.  "Who's coming to the store with me?"   "I am!"  or "Who's going to eat the last piece of cake?"  "I am!")

Answer 4

The two can be used almost interchangeably, however, "I'm" is a lot less formal than "I am". So, if you want to show a little respect, to say, a job interviewer, you might want to throw in a couple of "I am"s (but not too many, otherwise you might come off as "out of touch" or "stiff").

Or, if you want to sound like you are slightly distancing yourself from someone, such as someone you are angry or disappointed with, you can use "I am", but this is a rather subtle point which may not be understood by the person who is receiving this.

Hope this helps!
