No es culpable.

Because culpable here describes a person’s status or responsibility, not a temporary physical condition or location.

In Spanish, ser is normally used for things like identity, classification, or responsibility:

• Es culpable = He/She is guilty

Using estar with culpable would sound unnatural in standard Spanish. So No es culpable is the normal way to say it.

Spanish often leaves out subject pronouns when they are already understood from context. This is called subject pronoun omission.

So:

• No es culpable can mean He is not guilty, She is not guilty, or even It is not guilty, depending on context.

If you want to make the subject clear or add emphasis, you can include it:

• Él no es culpable
• Ella no es culpable

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

So:

• No es culpable = correct
• Es no culpable = incorrect in normal Spanish

This is the standard way to make a sentence negative.

Because culpable is an adjective that has the same form for both masculine and feminine singular.

So you can say:

• Él es culpable
• Ella es culpable

The adjective stays the same. Only the context tells you whether it refers to a man or a woman.

In the plural, culpable becomes culpables.

Examples:

• No son culpables = They are not guilty
• Los acusados no son culpables = The accused are not guilty

So the adjective does change for number, but not for gender.

A rough pronunciation for an English speaker is:

noh ess kool-PAH-bleh

A few details:

• No = like noh
• es = like ess
• culpable has the stress on pa: cul-PA-ble
• The final e is pronounced, not silent

In Spain, the c in culpable is a normal hard k sound because it comes before u.

Yes. By itself, it does not tell you the gender of the person.

Spanish often leaves that information out unless it is needed. If you need to specify, you can say:

• Él no es culpable
• Ella no es culpable

They are similar, but not always identical.

• No es culpable = He/She is not guilty; not legally or morally responsible
• No tiene la culpa = It is not his/her fault

Culpable often sounds a bit more formal or legal. Tener la culpa is very common in everyday speech when talking about blame.

Examples:

• No es culpable del crimen = He/She is not guilty of the crime
• No tiene la culpa de lo que pasó = It is not his/her fault what happened

They are close, but not the same.

• No es culpable = He/She is not guilty
• No es el culpable = He/She is not the guilty one / not the culprit

The version with el points more to a specific person being identified as the culprit. The version without el is more about the general idea of guilt.

Not in this sentence.

After ser, adjectives normally appear without an article:

• Es culpable
• Es inocente
• Es responsable

You would use an article if culpable is being used more like a noun:

• Es el culpable = He is the culprit

So in No es culpable, culpable is an adjective, not a noun.

No. Culpable is the normal word for guilty.

• Es culpable = He/She is guilty

Culpado exists, but it is much less common in modern everyday Spanish for this meaning, and learners should usually stick with culpable.

Yes. No es culpable is correct and natural in both formal and neutral contexts.

It can appear:

• in legal language
• in news reports
• in everyday conversation

In very casual speech, people might also say things like:

• No tiene la culpa
• No ha hecho nada

But No es culpable is perfectly standard and widely understood.
