Uses of Ser
Ser is used to talk about permanent or lasting attributes. If this general rule is too vague for you, think of the acronym DOCTOR, which stands for Descriptions, Occupations, Characteristics, Time, Origin, and Relationships. Let's take a look at each of the above categories individually.
Descriptions are the essential qualities that define a person or thing and probably won’t change anytime soon. These descriptions can be names, physical descriptions, nationalities, and even religions.
An occupation is what someone does for a living or as a hobby. Basically, if you're talking about how someone makes money or fills their time, you'll use ser.
Notice that the indefinite articles un, una, unos, and unasmay not be used when talking about occupations with ser. They're often only included if extra information following the occupation is given. Compare the following:
Characteristics are personality descriptions of a person. This category is included to hammer home the point that ser is used to talk about descriptions.
Time can refer to days, dates, years, and the time on the clock.
The place a person or thing is from or the material something is made of can be considered an origin.
Personal relationships, such as family ties, friendship, and romantic relationships, are also talked about using ser.
Uses of Estar
Estar is used to indicate temporary states and locations. If that general rule doesn’t suffice, there are two acronyms that you can think of, PLACE and LoCo. PLACE stands for Position, Location, Action, Condition, and Emotion. LoCo stands for Locations and Conditions. Let's look at PLACE now.
Position refers to the physical position or posture a person or thing is in.
The location of someone or something describes where it is permanently, temporarily, or conceptually.
Intriguingly, death in Spanish is seen as an ongoing action, not a permanent state, so estar is used to talk about being dead.
Physical and mental conditions are described using estar. Things that are likely to vary over several hours, days, or even years can fall into this category.
How a person is feeling at a certain moment is described using estar.
