There is only one set of endings in the imperfect subjunctive, regardless if the verb ends in -AR, -IR or -ER.
| Yo | ra |
| Tú | ras |
| Él, ella, usted | ra |
| Nosotros* | 'ramos |
| Vosotros | rais |
| Ellos, Ellas, Uds. | ran |
* Note: the Nosotros form has an accent on the vowel that immediately precedes the "r" in "-ramos."
You form the imperfect subjunctive by taking the third person plural (Ellos, ellas, ustedes) form of the preterite past tense, and then adding the appropriate Imperfect subjunctive ending.
For example:
| 1) Tener |
| 2) Tuvieron (the Preterite 3rd person plural) |
| 3) Drop the "-ron" ending: tuvie- |
| 4) Add one of the appropriate "-ra / -ras / -ra / -'ramos / -rais / -ran" endings |
Examples of the Imperfect Subjunctive:
| Hablar | Comer | Vivir | |
| Yo | hablara | comiera | viviera |
| Tú | hablaras | comieras | vivieras |
| Él, ella, usted | hablara | comiera | viviera |
| Nosotros | habláramos | comiéramos | viviéramos |
| Vosotros | hablarais | comierais | vivierais |
| Ellos, ellas, Uds. | hablaran | comieran | vivieran |
NOTE: There are two different endings for the Imperfect Subjunctive, ie -RA (the one dealt here) and -SE endings which is dealt with in another unit.
