Learn Spanish (Latin America): Bate los huevos para el desayuno.

When giving an affirmative command to someone you address as tú (informal "you"), you use the same form as the he/she/it present tense. You drop the final s from the normal tú form. So instead of tú bates (you beat), the command is just bate (beat!).

Which verb does bate come from, and how would I say this to an usted?

It comes from the verb batir (to beat or whisk). If you wanted to give this instruction formally to someone you address as usted, the command form changes its vowel to an "a", making it bata los huevos.

Why does this sentence use para instead of por for the word "for"?

We use para here because it shows the purpose or destination of the action. The eggs are destined to become breakfast. As a general rule for beginners, if you mean "intended for" or "with the goal of," para is usually the right choice.

Is the "h" in huevos silent?

Yes! In Spanish, the letter "h" is always silent, no matter where it is in a word. You pronounce huevos as if it were written "uevos" (WEH-vos).
