💡 Grammar Points
Transitive Use
When you use 'iniciar' in this way, it always needs to 'start' something directly. For example, 'iniciar el coche' (start the car).
❌ Common Pitfalls
Confusing Start/Begin
Mistake: "La clase inicia a las tres."
Correction: La clase empieza a las tres. ('Empezar' or 'comenzar' are usually better when the subject starts by itself, like a class or a movie.)
⭐ Usage Tips
Formal Context
Use 'iniciar' when the action is more official, like starting a formal process, a legal procedure, or a major project. It sounds more professional than 'empezar'.

When joining a group or learning a skill, iniciar means to be initiated.
iniciar(verb)
to be initiated
?into a group or skill
,to take up
?a hobby or career
to start (by itself)
?a fire, a conflict

💡 Grammar Points
The 'Se' Requirement
When you use 'iniciarse,' you must include the small word 'se' (or 'me,' 'te,' 'nos,' etc.) before the verb. This shows that the subject is starting itself or entering a new phase.
Linking Word 'En'
When talking about starting a new field or hobby, 'iniciarse' is almost always followed by the word 'en' (in/into): 'Se inició en el ajedrez' (He started in chess).
❌ Common Pitfalls
Missing the Pronoun
Mistake: "El proyecto inicia mañana."
Correction: El proyecto se inicia mañana. (If the project starts by itself, it needs the reflexive pronoun 'se' to show the action is contained within the subject.)
⭐ Usage Tips
Self-Starting Events
Use 'iniciarse' when something begins without a clear external agent, like a fire, a storm, or a conflict: 'El incendio se inició por un cortocircuito' (The fire started due to a short circuit).
