I´ve seen "içinde" and "içimde" in different text and wonder what the difference is, or is it just a spelling?

Also "bi" is something that people write, and it never makes sense. Do they mean "bir" or something else? And it seems common then, to write "bir" as "bi"?

It´s terribly confusing for us beginners. Bet there are more examples of people spelling words differently, that confuses us.

Nice question, Nixy, and to the point.

Look:

                      1. iç|im|de = ´inside of me´

                      2. iç|in|de = ´inside of you´

                      3. iç|i|n|de = ´insıde of him/her/it´

iç is a noun, it means ´inside´. -de is a locative ending, corresponding to English ´in´. What is in between shows whose inside the talk is about.

Unfortunately there are 2 x içinde. That is because there is a rule that a small -n- must be added between the third person possessive suffix and a case ending.

bir and bi...they are the same. Native speakers use bi a lot. It is an easy way to recognize them from the rest of the world.

"bi bakar mısın abicim?" So typical

Thank you Abla! Now I understand more.
