This form is used when the subject is plural: 'ellos' (they, masculine/mixed group), 'ellas' (they, feminine group), or 'ustedes' (you all, formal).

❌ Common Pitfalls

Working vs. Functioning

Mistake: "Misusing 'trabajan' (they work) for objects."

You can use 'funcionar' for abstract things like ideas, plans, or relationships: 'Nuestras ideas funcionan juntas' (Our ideas work together).

Frequently Asked Questions

When should I use 'funcionan' instead of 'trabajan'?

Use 'funcionan' when you are talking about objects, machines, processes, or systems performing their tasks (e.g., 'The computers work'). Use 'trabajan' when you are talking about people having a job or exerting effort (e.g., 'The employees work').

Is 'funcionan' formal or informal?

The word itself is neutral. However, if the subject is 'ustedes' (you all), it is the formal way to address a group. If the subject is 'ellos' or 'ellas' (they), it is simply a descriptive statement.
