Accents and accent patterns are very important in Spanish grammar. Do the Irregular verbs IR-SER-DAR-VER have accents when the conjugated in
PRETERITE tense?

Yea or no?

No

Explanation:

When placing accents in Spanish we must keep in mind that there are four types of words: agudas, llanas, esdrújulas and sobresdrújulas.

Agudas:
Are those words that’s have the stress on the last syllable.
-Camión
-Pintor
They carry an accent only when they end in n, s or in a vocal.

Llanas:
Are words in which the stress falls in the next to the last syllable.
Lápiz
Carta
They carry an accent only when they do not end in n, s or in a vocal.

Esdrújula
These are words that carry the accent in the third syllable and always have the accent mark.
Teléfono

Sobresdrújulas
These are words that carry the accent in the fourth syllable and always have the accent mark.
Alfabéticamente

The preterite tense of the irregular verbs IR, SER, DAR, VER are FUISTE, FUISTE, DISTE and VISTE.
They express a past action or state.

This words are Llanas because they carry the stress in the second syllable and do not need an accent mark because they end in E which is a vocal.

Hope this helps!
