Accents

In Spanish there are three main rules to applying accents.

  1. Words that are stressed on the last syllable are called agudas. If an aguda word ends in a consonant other than n or s it is written without an accent mark. If an aguda end in a vowel, or n or s it carries a written accent mark.

    Examples: canción , aquí, detrás

  2. Words that are stressed on the next to last syllable are called graves or llanas. If a grave word ends in a vowel or n or s it does not carry a written accent. If a grave ends in a consonant other than n or s it carries a written accent.

    Examples: ángel, lápiz, débil

  3. Words that are stressed on the third to the last syllable are called esdrújula. All esdrújula words carry a written accent.

    Examples: católico, estómago, magnífico

  4. Accent marks are also used to create hiato, that is to separate what would otherwise be dipthongs. Dipthongs are single syllables formed by the combination of a strong vowel (a, e, o) with a weak vowel (i, u), or two weak vowels. If the pronunciation of the word requires the weak vowel to be stressed, the weak vowel is accented.

    Examples: biología, país, púa
    Counter-examples: historia (dipthong, not hiato), miércoles (stress on strong vowel, not weak one, thus no hiato).

  5. Finally, quite a few homonyms use written accent marks to distinguish between their meanings. These must be memorized.

    Examples: = yes / si = if, más = more / mas = but

Verb Conjugations

1. Present indicative tense -ar, -er, -ir verbs

The present tense in Spanish is used to talk about actions that occur in the present or immediate future, or that commonly reoccur.

llegar (-ar) aprender ( -er) vivir ( -ir)
Yo llego aprendo vivo
llegas aprendes vives
Usted/ el/ ella llega aprende vive
Nosotros(as) llegamos aprendemos vivimos
Vosotros llegáis aprendéis vivís
Ustedes/ ellos/ ellas llegan aprenden viven


The present tense in Spanish corresponds to four possible English forms:
La profesora llega temprano. The professor arrives early.
The professor is arriving early.
The professor does arrive early.
The professor will arrive early.

A. Some verbs require a change in the stem vowel of the present indicative, all forms except nosotros and vosotros.

O > UE E>I E>IE U>UE
encontrar ( to find) medir ( to measure) perder ( to lose) jugar (to play sports)
encuentro mido pierdo juego
encuentras mides pierdes juegas
encuentra mide pierde juega
encontramos medimos perdemos jugamos
encontráis medís perdéis jugáis
encuentran miden pierden juegan

B. In the present tense there are also many irregular verbs in only the first person: YO. They may or may not have stem vowel changes also.

decir venir tener
digo decimos
dices decís
dice dicen
vengo venimos
vienes venís
viene vienen
tengo tenemos
tienes tenéis
tiene tienen
saber conocer salir
sabemos
sabes sabéis
sabe saben
conozco conocemos
conoces conocéis
conoce conocen
salgo salimos
sales salís
sale salen

2. Preterit

The preterit is used to express an action in the past that has been completed. It also can be used to represent a specific moment in an action whether that action is ongoing or completed or not..

Formation of the preterit tense of regular verbs -ar, -er, -ir verbs:

-ar -er & -ir
-amos
-aste -asteis
-aron
-imos
-iste -isteis
-ió -ieron

cerrar perder abrir
yo cerré perdí abrí
cerraste perdiste abriste
Ud./él/ella cerró perd abr
nosotros cerramos perdimos abrimos
vosotros cerrasteis perdisteis abristeis
Uds./ellos/ellas cerraron perdieron abrieron

A. In order to maintain the consonant sound of the infinitive, verbs that end in -car, -gar and -zar undergo a spelling change only in the YO form.

g > gu c > qu z > c
jugar buscar almorzar
jugué busqué almor
jugaste buscaste almorzaste

B. Other -er and -ir verbs whose stem ends in a vowel change the i in their third person singular and plural endings to y.

leer creer oír
leí creí
leíste creíste oíste
leyó creyó oyó
leímos creímos oímos
leyeron creyeron oyeron

C. Other irregular verbs have the same endings for -er and -ir, with some irregularities. These verbs have no written accents.

ir / ser tener decir
fui fuimos
fuiste fuisteis
fue fueron
tuve tuvimos
tuviste tuvisteis
tuvo tuvieron
dije dijimos
dijiste dijisteis
dijo dijeron
saber hacer dar
supe supimos
supiste supisteis
supo supieron
hice hicimos
hiciste hicisteis
hizo hicieron
di dimos
diste disteis
dio dieron

3. Imperfect

The imperfect is known as the descriptive past tense. It is used to describe repeated or continuous actions in the past, with no referance to the begining or end of the action. In order to form the imperfect of regular verbs, you must add the folllowing endings to the stem of the verb. There are no stem changing verbs with this tense.

-ar -er & -ir
-aba -ábamos
-abas -ais
-aba -aban
-ía -íamos
-ías -íais
-ía -ían

caminar comer
yo caminaba comía
caminabas comías
Ud./él/ella caminaba comí
nosotros (as) caminábamos comíamos
vosotros caminaís comíais
Uds./ellos/ellas caminaban comían


The Spanish imperfect has three common translations:
Yo vivía en la capital. I lived in the capital.
I was living in the capital.
I used to live in the capital.

There are only three irregular verbs in the imperfect:

ir(to go) ser(to be) ver(to see)
iba íbamos
ibas ibais
iba iban
era éramos
eras erais
era eran
veía veíamos
veías veíais
veía veían

Remember the written accent mark for all -er and -ir verbs, also first person plural (nosotros) of -ar verbs.

4. Present Subjunctive

Conjugate the present subjunctive by adding endings to the root formed by removing the ‘-o’ from the first person singular form of the present indicative (plain present tense). The characteristic vowel of present subjunctive endings is the opposite of the present indicative:

enseñar to teach aprender to learn escribir to write
(enseño) enseñe (aprendo) aprenda (escribo) escriba
enseñes aprendas escribas
enseñe aprenda escriba
enseñemos aprendamos escribamos
enseñéis aprendáis ecribáis
enseñen aprendan escriban

A. Stem changing -ar and -er verbs have the same pattern they have in the present indicative; -Ir verbs have an additional change in the first and second person plural forms:

e > ie o > ue e > i
pensar   to think dormir   to sleep repetir   to repeat
piense duerma repita
pienses duermas repitas
piense duerma repita
pensemos durmamos repitamos
penséis durmáis repitáis
piensen duerman repitan

B. Verbs that have irregular stems in the “yo” form of the present indicative use that root throughout the present subjunctive:

tener (tengo): tenga, tengas, tenga, tengamos, tengáis, tengan

venir (vengo): venga, vengas, venga, vengamos, vengáis, vengan

decir (digo): diga, digas, diga, digamos, digáis, digan

conocer (conozco): conozca, conozcas, conozca, conozcamos, conozcáis, conozcan

C. Numerous verbs in the subjunctive require spelling changes so the consonant in the root will conform to the new ending ( mainly the and soft ‘G’ and ‘C’ ):

pagar (to pay): pague, pagues, pague, paguemos, paguéis, paguen

escoger (to choose): escoja, escojes, escoja, escojamos, escojáis, escojan

cruzar (to cross): cruce, cruces, cruce, crucemos, crucéis, crucen

D. There are six irregular verbs:

ir (to go): vaya, vayas, vaya, vayamos, vayáis, vayan

ser (to be): sea, seas, sea, seamos, seáis, sean

estar (to be): esté, estés, esté, estemos, estéis, estén

saber (to know): sepa, sepas, sepa, sepamos, sepáis, sepan

haber (auxiliary verb): haya, hayas, haya, hayamos, hayáis, hayan

dar (to give): dé, des, dé, demos, deis, den

5. Imperfect Subjunctive

There is only one past tense in the subjunctive, the imperfect subjunctive. Form the root by removing the ‘-ron’ from the third-person plural of the preterit, then add endings as follows:

enseñar(to teach) aprender(to learn) escribir(to write)
(enseñaron) (aprendieron) (escribieron)
ensñara aprendiera escribiera
enseñaras aprendieras escribieras
enseñara aprendiera escribiera
enseñáramos aprendiéramos ecribiéramos
enseñarais aprendierais escribierais
enseñaran aprendieran escribieran

A. Any irregularities that applied to the preterit form will apply here; there are no additional irregularities.

ir/ser: (fueron) fuera, fueras, fuera, fuéramos, fuerais, fueran

dormir: (durmieron) durmiera, durmieras, durmiera, durmiéramos, durmierais, durmieran
