Learn Spanish (Latin America): Mi papá no come pan.

In Spanish, possessive words like mi have to match the amount of the things being owned, not the amount of owners. Since papá is just one person, you use the singular mi. If you were talking about both of your parents, you would use the plural and say mis papás.

Why is there an accent mark on the last letter of papá?

That accent mark is very important! It tells you to stress the last syllable when speaking. Without it, the word papa means potato. So without the accent mark, your sentence would mean that your potato does not eat bread.

Where is the word for "does" in the Spanish sentence?

Spanish does not use helper words like "does" or "do" to make a sentence negative. Instead of saying "does not eat", you simply put no right in front of the main verb. So no come translates perfectly to "does not eat".

Why is the verb come and not como?

In Spanish, verbs change their endings based on who is doing the action. Como means "I eat". Since the person doing the action here is mi papá (which falls under the "he" category), we use the "he" or "she" ending for the verb comer, which is come.
