- Number: Add ‑s for plural forms (únicos, útiles, urgentes, universales).
- Placement: Descriptive adjectives usually follow the noun, but many can precede it for emphasis, stylistic flair, or to convey a subjective nuance (e.g., un único oportunidad vs. una oportunidad única).
- Position with adverbs: When modified by adverbs like muy, bastante, or **poco
