💡 Grammar Points
Using 'Con'
When 'cumplir' means 'to comply with' a rule or requirement, it is often followed by the little word 'con': 'Tienes que cumplir con las normas' (You have to comply with the rules).
⭐ Usage Tips
Action vs. Result
Think of 'cumplir' as the action of completing a full requirement, whereas 'terminar' (to finish) usually refers to ending a task.

💡 Grammar Points
Age Expression
In Spanish, we use 'cumplir' directly with the number: 'Cumplo 30' (I turn 30). You do not need to say 'años' unless you want to emphasize 'years'.
❌ Common Pitfalls
Using Tener
Mistake: "Mañana tengo 30 años."
Correction: Mañana cumplo 30 años. ('Tener' is for current age, 'cumplir' is for the transition/birthday.)

Cumplir meaning a wish or prediction has 'come true'.

expire
?a term limit or sentence
📝 In Action

B2His dream of traveling the world finally came true.
La profecía se cumplirá al pie de la letra.
C1The prophecy will be realized exactly as written.
💡 Grammar Points
Reflexive Use
When the verb is used to mean 'come true' or 'be realized,' it must include the reflexive pronoun 'se' (cumplirse). The object (the dream, the prophecy) performs the action on itself.

Frequently Asked Questions
What is the difference between 'cumplir' and 'terminar'?
'Terminar' simply means 'to finish' or 'to end' a task or process. 'Cumplir' means 'to fulfill' or 'to carry out' something completely, often implying a moral duty or legal requirement. You can 'terminar' a project, but you 'cumplir' a contract.
Does 'cumplir' always require 'con'?
No. When you are fulfilling a direct object (like a promise or a contract), you don't need 'con': 'Cumplí la promesa.' You usually use 'con' when you are complying *with* a rule or standard: 'Cumplí con las reglas.'
