Hacer trampa no es justo.

In Spanish, an infinitive can act like a noun or a whole activity. Here, hacer trampa means cheating or to cheat as a general action.

So Hacer trampa no es justo is structured like:

• Hacer trampa = cheating / to cheat
• no es justo = is not fair

Spanish often uses the infinitive this way:

• Fumar es malo. = Smoking is bad.
• Mentir no está bien. = Lying is not okay.

Hacer trampa is a fixed expression that means to cheat.

Even though hacer usually means to do or to make, and trampa can literally mean trap, trick, or deception, the full phrase hacer trampa means to cheat in games, tests, competitions, and similar situations.

Examples:

• No hagas trampa en el examen. = Don’t cheat on the test.
• Hizo trampa para ganar. = He/She cheated to win.

So it is best learned as one unit: hacer trampa = to cheat.

Because hacer trampa is an idiomatic expression. In this phrase, Spanish normally does not use an article.

So you say:

• hacer trampa = to cheat

Not usually:

• hacer una trampa for this meaning

If you say una trampa, it usually sounds more like a trap or a trick, not the general action of cheating.

Because the subject of the sentence is the infinitive phrase hacer trampa, and infinitive phrases are treated as singular and usually take masculine agreement when an adjective describes them.

So:

• Hacer trampa no es justo.
• Mentir es malo.
• Estudiar es importante.

Even though trampa is a feminine noun by itself, the adjective is not agreeing with trampa alone. It is describing the whole action hacer trampa.

Spanish uses ser here because justo means fair in the sense of a general quality or judgment.

• ser justo = to be fair / just
• estar is usually for states, conditions, or locations

Here, the speaker is saying that cheating is unfair in general, so ser is the natural choice:

• No es justo. = It’s not fair.

Using estar justo would usually mean something very different, depending on context, such as to be exact or to be tight.

Here, justo means fair or just.

So no es justo means:

• it’s not fair
• it isn’t just

In everyday speech, justo often means fair in moral or social situations:

• Eso no es justo. = That’s not fair.
• Es una decisión justa. = It’s a fair decision.

Yes. No es justo hacer trampa is also correct.

Both versions are natural:

• Hacer trampa no es justo.
• No es justo hacer trampa.

The difference is mostly one of focus:

• Hacer trampa no es justo starts by highlighting the action itself.
• No es justo hacer trampa starts with the judgment it’s not fair.

Both are common and correct.

In Spanish, no normally goes directly before the conjugated verb.

Here, the conjugated verb is es, so:

• Hacer trampa no es justo.

Not:

• Hacer no trampa es justo
• No hacer trampa es justo unless you mean Not cheating is fair, which is a different sentence

So in this sentence, no negates es:

• no es = is not

Yes. Hacer trampa is very common and widely understood across Latin America.

It is a standard way to say to cheat, especially in games, sports, and school contexts.

Depending on the country or situation, you might also hear more specific verbs or expressions, but hacer trampa is a very safe, broadly useful phrase for learners.

For example:

• In school contexts, some places may also use verbs related to copying on a test.
• In broader contexts, engañar can mean to deceive, but that is not exactly the same as hacer trampa.

Sometimes yes, depending on region and context, but hacer trampa is a very common standard expression and is the safest one to learn first.

In this sentence, hacer trampa is completely natural. As a learner, you should treat it as a set phrase.

So if your goal is to say to cheat, hacer trampa is an excellent choice.
