@TheCubingCuber347, that's not really a grammatically correct translation. "Nam" does mean "for", but not correctly in this instance. "Pro," a Latin preposition, would be a more adequate word to use in this instance, meaning "on behalf of" or "for." This preposition takes the the ablative case, so the translation would be "Pro anates."(Continued)
However, this is grammatically a fragment, meaning it does not have a subject and predicate. So we can add a verb to make this sentence grammatically correct, with the verb "est," a form of the being verb, "sum." "Est" means "it is," and we can imply this in the sentence to make it grammatically correct. Therefore, the correct translation would be "Pro anates est," meaning "(It is) for the ducks!"
I assume you used Google Translate for your original translation, and you need to know in the future, Google Translate for Latin seriously messes things up haha
