How can I tell the difference between Ser and Estar?
When do I use ser and estar in a Spanish sentence?
4 Answers
Ser is used with:
Elements pertinent to your identity: physical description, personality and character, nationality, race, gender, profession, origen
Things which "Take Place" or "Occur": Dates, days, seasons, time, events, concerts, parties
What things are made of
Possession
Estar is used with
Feelings/moods/emotions, physical conditions or appearances, civil status (married, single, divorced, dead)
Location of things and people (but not events)
Present Progressive tense (the immediate "-ing" form)
Ser vs. Estar
Some adjectives have different meanings depending upon which form of "to Be" you use. Generally, if you use Ser, the adjective is a characteristic of the person or thing you are describing; whereas if you use Estar, it is a description of a mood or appearance.
You may have heard that Ser is used for things which are permanent and Estar is used for things which are temporary. This is an over-simplification and not a good way to think of these verbs because you will end up with a lot of exceptions and confusion. Try to forget you ever heard that.
It is better to remember that Ser pertains to Identity (with all of its elements) and that Estar pertains to States of Being: Condition, Location, and the Present Progressive.
