What is the error in each sentence below. Re-write the sentences correctly and explain the error in each sentence.

Yo nadar
Ellos cantamos
Yo cantas

Can you please tell me the answers and how to explain it

1. Original: "Yo nadar"

Error: The error in this sentence is that there is a verb missing. The word "nadar" is an infinitive form of the verb, but it is not conjugated to match the subject "Yo" (which means "I" in Spanish).

Correction: "Yo nado"
Explanation: In Spanish, verbs need to be conjugated to match the subject. The correct conjugation of the verb "nadar" for the subject "Yo" is "nado", which means "I swim".

2. Original: "Ellos cantamos"
Error: The error in this sentence is that the verb conjugation does not match the subject. The subject "Ellos" means "they", but the verb "cantamos" is the first-person plural form of the verb, which means "we sing".

Correction: "Ellos cantan"
Explanation: The correct conjugation of the verb "cantar" for the subject "Ellos" is "cantan", which means "they sing".

3. Original: "Yo cantas"
Error: The error in this sentence is that the verb conjugation again does not match the subject. The subject "Yo" means "I", but the verb "cantas" is the second-person singular form of the verb, which means "you sing".

Correction: "Yo canto"
Explanation: The correct conjugation of the verb "cantar" for the subject "Yo" is "canto", which means "I sing".

I don't know Spanish, but I do know that subjects and verbs must "match" -- that is, if you have a first person singular subject, you'd better have the right singular verb form to match it.

Study what these terms mean, and then apply them to your sentences.

first person singular
first person plural
second person singular
second person plural
third person singular
third person plural

Someone will be glad to check your answers.
