Ser vs Estar (Basic Uses)
Master the two Spanish 'to be' verbs with the DOCTOR and PLACE memory tricks
The rule at a glance
ser = what something is · estar = how or where it is
SER: DOCTOR (Description, Occupation, Characteristic, Time, Origin, Relationship) · ESTAR: PLACE (Position, Location, Action, Condition, Emotion)
Ser (DOCTOR)
soy · eres · es
identity, job, origin, time
Soy profesor y soy de Madrid.
I'm a teacher and I'm from Madrid.
Estar (PLACE)
estoy · estás · está
location, mood, condition
Hoy estoy cansado y estoy en casa.
Today I'm tired and I'm at home.
Same word, new meaning
es aburrido / está aburrido
he is boring / he is bored
La película es aburrida, así que estoy aburrido.
The film is boring, so I'm bored.
- Location takes estar, even when it never changes: Madrid está en España. Events are the exception: La fiesta es en mi casa.
- Feeling hot? Say Tengo calor, never Soy caliente or Estoy caliente.

I am a teacher (identity)
I am in London (location)
I am happy (temporary)
I am a teacher (identity)

The Dangerous "Soy caliente" Mistake!
NEVER say: Soy caliente

Say instead: Tengo calor
"I have heat" = I feel hot (temperature)
Tricky Exceptions & Special Cases
Death & Marriage
Está muerto (he is dead)
Está casado (he is married)
Uses ESTAR because these are states, not inherent characteristics
