How to Say "toxic" in Spanish

English → Spanish

tóxico

adjectiveA2general
Use 'tóxico' for things that are literally harmful to health or have a negative emotional impact, like chemicals or a stressful environment.

Examples

Be careful, those cleaning products are toxic.

venenoso

/beh-neh-NOH-soh//be.neˈno.so/

adjectiveA2general
Use 'venenoso' for things that contain poison, like certain plants or animals, or to describe spiteful or malicious comments and personalities.

The cleaning product is poisonous if swallowed.

One word for two English concepts

In English, we say 'venomous' for animals that bite and 'poisonous' for things you eat. In Spanish, 'venenoso' is the all-in-one word for both!

Gender matching

If you are describing something feminine, like 'una araña' (a spider), you must change the ending to 'a': 'una araña venenosa'.

Figurative usage

Just like in English, you can use physical 'poison' words to describe people's behavior. It functions exactly like an adjective describing a person's character.

Using the wrong 'to be'

Mistake:Está venenoso.

Correction: Es venenoso. Use 'ser' because being poisonous is a permanent characteristic of that thing.

Intensity

envenenado

/en-ben-en-ah-doh//embenenˈaðo/

adjectiveB2general
Use 'envenenado' when referring to a situation, relationship, or atmosphere that has been corrupted or made negative by something harmful, like bitterness or resentment.
A grumpy-looking cartoon storm cloud with a sharp frown and dark shadows under its eyes.

Examples

Él tiene un corazón envenenado por el rencor.

He has a heart poisoned by resentment.

Lanzó un comentario envenenado contra su rival.

He made a spiteful comment against his rival.

Figurative description

When describing a person's character, we usually use the word 'corazón' (heart) or 'alma' (soul) together with 'envenenado'.

Tóxico vs. Venenoso vs. Envenenado

Learners often confuse 'tóxico' and 'venenoso.' Remember that 'tóxico' is broader and often relates to health or general harm, while 'venenoso' specifically implies poison or malicious intent. 'Envenenado' is more about a corrupted state, often emotional or relational.
