Learn Spanish (Latin America): Uno protege el honor siempre que defienda la escuela. - One protects honor as long as one defends the school.

Uno is an impersonal pronoun that translates to "one" or a general "you" in English. It is perfect for making general statements or rules that apply to anyone. Notice that it always takes a third-person singular verb, which is why we use protege and defienda.

Why is there an el before honor?

In Spanish, abstract concepts and nouns used in a general sense require a definite article (el, la, los, las). Because this sentence refers to the general concept of honor rather than a specific instance, it must be el honor.

Does siempre que literally mean "always that"?

Literally yes, but it translates to "as long as" or "provided that" when setting a condition, which is what's happening in this sentence. It can also mean "whenever" or "every time that" in other contexts.

Why is the verb defienda in the subjunctive mood here?

The conjunction siempre que triggers the subjunctive when it means "as long as" or "provided that." It introduces a requirement or a condition that might or might not be fulfilled. Because this condition is hypothetical, we need the subjunctive defienda.
