💡 Grammar Points
Gender and Articles
When using 'ex' to talk about a person, the word 'ex' itself doesn't change based on gender, but the article that goes before it does: 'el ex' (male) or 'la ex' (female).
❌ Common Pitfalls
Confusing Gender
Mistake: "Usar 'la ex' para un hombre."
Correction: Use 'el ex' for a man and 'la ex' for a woman, regardless of the word's appearance.
⭐ Usage Tips
Short and Sweet
Even though 'ex' is technically a shortened version of 'expareja,' native speakers almost universally use the short form 'mi ex' in casual conversation.

As a prefix, "ex-" can mean "former," indicating a previous status or position.

💡 Grammar Points
Prefix Rule: Hyphens
The Spanish Royal Academy mandates that 'ex-' must be written separately from the word it modifies, connected by a hyphen, when referring to a title or position (e.g., 'ex-profesor').
❌ Common Pitfalls
Incorrect Spacing
Mistake: "Escribir 'expresidente' o 'ex presidente'."
Correction: The correct modern spelling is always with a hyphen: 'ex-presidente'. Avoid writing it as one word or two separate words without a hyphen.
⭐ Usage Tips
Always Before the Noun
When used as a 'former' prefix, 'ex-' always comes right before the noun it modifies (e.g., 'la ex-alcaldesa'), never after.

The prefix "ex-" can also mean "out of," referring to direction or origin of movement.
📝 In Action

C1In the word 'extraer' (to extract), 'ex-' means taking something outward.
La raíz 'ex' en 'excelente' sugiere que la calidad va más allá de lo esperado.

Frequently Asked Questions
Does 'ex' change for masculine or feminine people?
The word 'ex' itself is invariable (it always stays the same), but the articles and adjectives around it change. Use 'el ex' for a man and 'la ex' for a woman. For example, 'mi guapo ex' (my handsome ex) vs. 'mi guapa ex' (my beautiful ex).
When should I use a hyphen with 'ex-'?
Always use a hyphen when 'ex-' is attached to a title or position (ex-jefe, ex-director). Do NOT use a hyphen when 'ex' is acting as a standalone noun for a partner ('mi ex').
