💡 Grammar Points

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'.

❌ Common Pitfalls

Forgetting the Plural

Mistake: "Muchos actos ilegal."

Correction: Muchos actos ilegales. (The adjective must end in '-es' when describing plural nouns.)

⭐ Usage Tips

Use 'Ilegal' for Laws, 'Prohibido' for Rules

Use 'ilegal' when referring to things that break official, governmental laws. Use 'prohibido' (forbidden) for simple rules or signs (e.g., 'Prohibido fumar'—Smoking forbidden).

💡 Grammar Points

Adjective Used as a Noun

Sometimes, Spanish speakers drop the person's identity and use the adjective 'ilegal' directly as a noun to refer to that person (e.g., 'el ilegal' or 'la ilegal'). This is a common pattern for many descriptive adjectives in Spanish.

⭐ Usage Tips

Be Sensitive: Use Alternatives

In modern, respectful language, it is strongly recommended to use 'indocumentado/a' (undocumented) or 'persona sin estatus legal' (person without legal status) instead of using 'ilegal' as a noun for a person, as the latter can be seen as offensive or dehumanizing.

Frequently Asked Questions

Does 'ilegal' change gender?

No, not like 'rojo' (roja). 'Ilegal' ends in '-l,' which means it stays the same for both masculine and feminine nouns (e.g., 'el coche ilegal' and 'la acción ilegal'). However, it does change to 'ilegales' when describing plural things.

What is the difference between 'ilegal' and 'prohibido'?

'Ilegal' is used for actions that break serious laws enforced by the government (like drug trafficking). 'Prohibido' (forbidden) is generally used for rules or regulations set by an authority (like 'No parking' or 'No smoking').
