How to Say "illegal" in Spanish
The most common Spanish word for “illegal” is “ilegal” — use 'ilegal' when you want to state directly that something is against the law or not permitted by legal standards..
ilegal
ee-leh-GAHL/i.leˈɣal/
Examples
Fumar en este edificio es completamente ilegal.
Smoking in this building is completely illegal.
La venta de ese producto se declaró ilegal.
The sale of that product was declared unlawful.
Cometió un acto ilegal al robar el coche.
He committed an illegal act by stealing the car.
Agreement is Key
Like many Spanish adjectives, 'ilegal' must match the number of the noun it describes (e.g., 'prácticas ilegales'). Luckily, it stays the same for masculine and feminine nouns because it ends in '-l' (e.g., 'el acto ilegal,' 'la acción ilegal').
Always Appears After the Noun
In Spanish, descriptive adjectives like 'ilegal' almost always come after the noun they modify: 'una práctica ilegal', not 'una ilegal práctica'.
Forgetting the Plural
Mistake: “Muchos actos ilegal.”
Correction: Muchos actos ilegales. (The adjective must end in '-es' when describing plural nouns.)
ilegales
ee-leh-GAH-lehs/ileˈɣales/
Examples

The sale of those substances is completely illegal and the authorities are investigating.

Illegal downloads have greatly affected the music industry.
Agreement is Key
Since 'ilegales' is a plural adjective, it must match the noun it describes in number (plural) and gender (masculine or feminine). It works for both: 'acciones ilegales' (feminine) and 'negocios ilegales' (masculine).
criminal
kree-mee-NAHL/kɾimiˈnal/
Examples

The police are investigating the group's criminal activities.

The lawyer said there was no proof of criminal intent.
Fue un error, no un acto criminal.
It was a mistake, not a criminal act.
Always the Same
As an adjective, 'criminal' is one of those words that stays the same whether the noun it describes is masculine (un acto criminal) or feminine (una intención criminal).
criminales
kree-mee-NAH-les/kɾimiˈnales/
Examples
Las actividades criminales deben ser erradicadas.
Criminal activities must be eradicated.

The lawyer studied the country's criminal laws.
Adjective Agreement
When used as a describing word (adjective), 'criminales' must match the thing it describes. Since 'criminales' is plural, the thing it describes must also be plural (e.g., 'actividades' or 'códigos').
Using the Singular Form
Mistake: “Las actividades criminal (missing the plural 'es')”
Correction: Make sure the adjective matches the noun: 'Las actividades criminales'.
