Comes from the Latin verb *unīre*, meaning 'to make one.' The Spanish word 'unir' means 'to unite something else,' and adding the reflexive 'se' turns the action back on the subject, making it 'to unite oneself' or 'to join.'

First recorded: Medieval Latin period (developed from Vulgar Latin)

Frequently Asked Questions

What is the difference between 'unir' and 'unirse'?

'Unir' is non-reflexive and means 'to unite or join two separate things' (e.g., 'I join the cables'). 'Unirse' is reflexive and means 'to join *oneself*' to something (e.g., 'I join the team') or 'to come together mutually' (e.g., 'The countries unite').

How do I say 'join us' using the command form?

For a friendly command (tú), you would say '¡Únete a nosotros!' The reflexive pronoun 'te' attaches to the end of the verb and changes to 'te' in the affirmative command.
