The whole system on one screen
| Pattern | ser | estar |
|---|---|---|
| Preterite | | |
| Imperfect | | |
| + participle | construida (was built) | (is shut) |
| + gerund | never | (it's raining) |
| + | (clever) | (ready) |
sits in the solid blue box and in the dashed pink one, on every example on this page.
Ser vs estar in the past tense
The past adds a second decision, not a new rule. Choose or as you would in the present, then choose preterite or imperfect as for any verb (preterite vs imperfect covers that half).
| Why | Spanish | English |
|---|---|---|
| where an event was | . | The party was at my house. |
| condition, a period | . | I was ill for two weeks. |
| origin, background | Sevilla. | My grandmother was from Seville. |
| condition, the scene | . | I was tired (at the time). |
| a day summed up | . | It was a very long day. |
The usual slip is not against but against . Describing the scene takes the imperfect:
.- The house was big. (description).- It was a hard year. (the year as a whole, now over)
Ser and estar in the other tenses
The preterite and the imperfect are the two you need now:
| Person | fue (ser) | era (ser) |
|---|---|---|
| yo | | |
| | |
| , , | | |
| | |
| | |
| , | | |
| Person | estuvo (estar) | estaba (estar) |
|---|---|---|
| yo | | |
| | |
| , , | | |
| | |
| | |
| , | | |
The preterite of is the same as the preterite of (to go). Context settles it:
.- I was a teacher.Madrid.- I went to Madrid.
The other tenses, one form each (the Spanish verbs pages have every person):
| Tense, yo form | ser | estar |
|---|---|---|
| Future | | |
| Conditional | | |
| Pres. subj. | | |
| Past participle | | |
| command | | estate |
.- Be patient.Madrid.- I'been to Madrid.Estate .- Keep calm.
Having visited a place takes , as the second line shows. The plain command of is , but everyday Spanish usually prefers the reflexive estate (from ), as in the third line.
Estar plus the gerund: actions in progress
Spanish builds its continuous forms with plus the gerund, never . The trigger is describing what is happening, not that it is temporary:
.- I'm eating..- It's raining..- We were talking.
The present progressive page has the gerund forms and when Spanish prefers the plain present.
Ser plus participle vs estar plus participle
English says "was" for both of these, and Spanish does not.
| Pattern | Spanish | English |
|---|---|---|
| : the action | construida 1920. | The house was built in 1920. |
| : the state | terminada. | The house is finished. |
| : the action | . | The door was shut at ten. |
| : the state | . | The door is shut. |
If you mean "it is in a shut state", you want . The passive with ser page covers the full passive, and why everyday Spanish often prefers instead.
The meaning-shifting pairs
Some adjectives change meaning with the verb. pulls the adjective into what someone is; into how they are now.

| bad (a person) | ill, off (food) |

| safe, reliable | sure; safe (here) |
| lively, sharp | alive |
| green | unripe |
| proud, haughty (a trait) | proud of something |

| proud of | . | He's proud of his daughter. |
One warning: said of a person, or is slang for attractive. Compliment the food, not the cook, with .
The cases that break the framework

| Case | Spanish | English |
|---|---|---|
| dead: a state | . | My grandfather is dead. |
| happy in life | . | He's a happy person. |
| happy now | . | I'm happy with the house. |
| calendar, idiom | . | It's winter. (we are in) |
| calendar, plain | . | It's Monday. |
and are idioms for where we are in the calendar; the plain statement of a day or date uses : .

| . (shut) | . | a state takes |
| . | . | death is a state |
| . | . | for bored, a state |
