It is generally used to portray permanent situations, for example: I am from Spain, he is a profesor, she is tall, this watch is my mother's etc. You'll find that this particular verb is one of the most versatile out there, but also hugely irregular, following almost no rules. Ser is not to be confused with Estar, also meaning "to be", but used for different situations.
