Final answer:
The proper form of the word when writing about yourself (yo) and the verb ends in -ir or -er is the first person singular form in Spanish.
Step-by-step explanation:
When you are writing about yourself (yo) and the verb ends in -ir or -er, the proper form of the word is the first person singular form. In Spanish, the first person singular form of verbs that end in -ir is formed by removing the -ir ending and adding the appropriate ending:
- For regular -ir verbs, you add the ending -o, for example: yo escribo (I write).
- For regular -er verbs, you add the ending -o, for example: yo como (I eat).
It is important to remember that this form is only used when you are referring to yourself (yo).
