Fully understanding what the subjunctive is used for is difficult to comprehend for many English speakers as it is an area of grammar rarely studied in English, due to the fact that the subjunctive is seldom used. However, in Spanish, the subjunctive is widely used and as such must be studied thoroughly.
Before looking further into the many irregularities that are commonplace within the subjunctive at is advisable, as it was when first being introduced to Spanish verbs, to start with the most basic of conjugations…the subjunctive present tense regular.
Regular Verbs in the Subjunctive Present Tense
Conjugating regular verbs in the subjunctive is quite straight forward as the examples below show;
Regular -ar Verbs
If you take the present tense conjugation of the indicative (shown on the left of the example) and change the ‘a’ in the ending (‘o’ in the first person singular) to an ‘e’ :
Hablar – to speak
- Hablo hable
- Hablas hables
- Habla hable
- Hablamos hablemos
- Habláis habléis
- Hablan hablen
Regular -er Verbs
Exactly the same as the regular -er verb except you change the ‘e’ in the ending (‘o’ in the first person singular) to an ‘a’:
Comer- to eat
- como coma
- comes comas
- come coma
- comemos comamos
- coméis comáis
- comen coman
Regular -ir Verbs
Simply remove the present tense endings and replace them with the same endings as used for the present tense subjunctive -er verbs:
Abrir- to open
- abro abra
- abres abras
- abre abra
- abrimos abramos
- abrís abráis
- abren abran
Regular Stem-Changing Verbs
It should also be noted that -ar and -er stem changing verbs carry over the same stem changing characteristics from the indicative present tense and also follow the regular pattern of change in the subjunctive as above. However, stem changing -ir verbs do not and are irregular.
Cerrar – to close
- cierro cierre
- cierras cierres
- cierra cierre
- cerramos cerremos
- cerráis cerréis
- cierran cierren
Mover – to move
- muevo mueva
- mueves muevas
- mueve mueva
- movemos movamos
- movéis mováis
- mueven muevan
