💡 Grammar Points
Agreement is Key
Since 'nervioso' is an adjective, you must change the ending to match the person or thing you are describing. Use '-a' for feminine words (nerviosa), and '-os' or '-as' for plurals (nerviosos, nerviosas).
Use 'Estar' for Feelings
To express feeling nervous, always use the verb 'estar' (to be) because it describes a temporary emotional state, not a permanent characteristic.
❌ Common Pitfalls
Using 'Ser'
Mistake: "Soy nervioso."
Correction: Estoy nervioso.

Frequently Asked Questions
How do I say that someone is a naturally nervous person?
While we usually use 'estar' to describe feeling nervous right now ('Estoy nervioso'), you can use 'ser' (Ser nervioso/a) to describe someone who is generally anxious or easily stressed as part of their character.
What is the difference between 'nervioso' and 'ansioso'?
'Nervioso' usually means you feel agitated or restless, often due to a known event (like a test). 'Ansioso' is slightly stronger and means 'anxious' or 'eager,' often involving a feeling of distress or worry about the future.
