💡 Grammar Points
Using 'Hacer' for Time
The phrase 'hace siglos' is key for saying 'ages ago.' It uses the verb 'hacer' (to do/make) to indicate a period of time elapsed: 'Hace [time period] que [event happened].'
❌ Common Pitfalls
Mixing up 'por' and 'hace'
Mistake: "Esperé por siglos."
Correction: Esperé siglos / Llevo esperando siglos. You usually don't need 'por' when using 'siglos' to mean 'a long time.'
⭐ Usage Tips
Expressive Language
Use 'siglos' when you want to sound dramatic or emphasize boredom or impatience. It is a very natural way to exaggerate in Spanish.

Frequently Asked Questions
If 'siglo' is singular, why is 'siglos' (plural) so often used for exaggeration?
Using the plural 'siglos' helps emphasize the vastness of the time period, making the exaggeration more dramatic. It's a common pattern in Spanish to use plurals for emphasis (like 'gracias' instead of 'gracia').
¿Siglos is masculine or feminine?
Since the singular form 'siglo' ends in -o, 'siglos' is a masculine noun. You must always use masculine words like 'los' or 'muchos' with it.
