Ser/estar

What is the difference between 'ser' and 'estar' ?


In Spanish, there are two words for 'to be': 'ser' and 'estar'. Generally, 'ser' describes more or less permanent qualities, and 'estar' is used for momentary conditions: for example, 'ella es alegre' means 'she is (always) happy', while 'ella está alegre' means 'she is happy (in this moment)'. Anyway, there are lots of other situations where the differences are not always obvious. Look at the following table to see specific situations when you must use 'ser' or 'estar'.

' El diccionario está en la mesa'. (= The dictionary is on the table.)
