-ir and -er ending verbs are very similar in their endings when they are conjugated. How do they differ in their endings when they are conjugated?

please don't tell me the answer using other peoples explanations.

The -ir and -er ending verbs differ in their endings when they are conjugated in the present tense. Specifically, in the singular form (yo, tú, él/ella/usted), -er ending verbs typically end in -o, while -ir ending verbs end in -o as well. However, in the plural form (nosotros/nosotras, vosotros/vosotras, ellos/ellas/ustedes), -er ending verbs usually end in -emos, while -ir ending verbs end in -imos.

When -ir and -er verbs are conjugated in Spanish, they have similar endings for some forms, but differ in others. Here is a breakdown of their conjugations:

For -ir verbs:
- The present tense endings for singular subjects (yo, tú, él/ella/usted) are: -o, -es, and -e respectively.
- The present tense endings for plural subjects (nosotros/nosotras, vosotros/vosotras, ellos/ellas/ustedes) are: -imos, -ís, -en respectively.
- The preterite tense endings for singular subjects (yo, tú, él/ella/usted) are: -í, -iste, -ió respectively.
- The preterite tense endings for plural subjects (nosotros/nosotras, vosotros/vosotras, ellos/ellas/ustedes) are: -imos, -isteis, -ieron respectively.
- The imperfect tense endings for singular subjects (yo, tú, él/ella/usted) are: -ía, -ías, -ía respectively.
- The imperfect tense endings for plural subjects (nosotros/nosotras, vosotros/vosotras, ellos/ellas/ustedes) are: -íamos, -íais, -ían respectively.

For -er verbs:
- The present tense endings for singular subjects (yo, tú, él/ella/usted) are: -o, -es, and -e respectively.
- The present tense endings for plural subjects (nosotros/nosotras, vosotros/vosotras, ellos/ellas/ustedes) are: -emos/-imos, -éis/-ís, -en respectively.
- The preterite tense endings for singular subjects (yo, tú, él/ella/usted) are: -í, -iste, -ió respectively.
- The preterite tense endings for plural subjects (nosotros/nosotras, vosotros/vosotras, ellos/ellas/ustedes) are: -imos, -isteis, -ieron respectively.
- The imperfect tense endings for singular subjects (yo, tú, él/ella/usted) are: -ía, -ías, -ía respectively.
- The imperfect tense endings for plural subjects (nosotros/nosotras, vosotros/vosotras, ellos/ellas/ustedes) are: -íamos, -íais, -ían respectively.

In summary, -ir and -er verbs have similar endings in the present tense for singular subjects, preterite tense for singular subjects, and imperfect tense for both singular and plural subjects. However, the present tense, plural forms, and preterite tense endings for plural subjects differ between -ir and -er verbs.

To understand the differences between -ir and -er ending verbs when they are conjugated, it's important to know the basics of verb conjugation in Spanish.

In Spanish, verbs are conjugated according to the subject pronoun (I, you, he/she, we, they) and the specific verb ending that corresponds to that subject. The verb endings change depending on whether the verb ends in -ar, -er, or -ir.

Let's first focus on the -er ending verbs. Here is a breakdown of how -er verbs are conjugated in the present tense:

- Yo (I): -o
- Tú (You): -es
- Él/Ella/Usted (He/She/You formal): -e
- Nosotros/Nosotras (We): -emos
- Ellos/Ellas/Ustedes (They/You all): -en

To give you a concrete example, let's use the verb "comer" (to eat):

- Yo como (I eat)
- Tú comes (You eat)
- Él/Ella/Usted come (He/She/You formal eats)
- Nosotros/Nosotras comemos (We eat)
- Ellos/Ellas/Ustedes comen (They/You all eat)

Now, let's move on to the -ir ending verbs. Here is how -ir verbs are conjugated in the present tense:

- Yo (I): -o
- Tú (You): -es
- Él/Ella/Usted (He/She/You formal): -e
- Nosotros/Nosotras (We): -imos
- Ellos/Ellas/Ustedes (They/You all): -en

For example, let's use the verb "vivir" (to live):

- Yo vivo (I live)
- Tú vives (You live)
- Él/Ella/Usted vive (He/She/You formal lives)
- Nosotros/Nosotras vivimos (We live)
- Ellos/Ellas/Ustedes viven (They/You all live)

From the comparison above, you can see that the -ir ending verbs differ from -er ending verbs in two forms: nosotros/nosotras and ellos/ellas/ustedes. -er ending verbs use -emos and -en endings, while -ir ending verbs use -imos and -en endings.

By understanding the basic conjugation patterns for -er and -ir verbs and applying them to specific verbs, you can easily distinguish the differences in their endings when they are conjugated. Remember, practice makes perfect, so keep practicing and using verbs in various contexts to solidify your understanding.
