how do you say ''live life''
how do you say live life , is the correct way "vida viva" or "vivir la vida", its for a tattoo.
You need to use the imperative because it's a command so you have two options:
¡Viva la vida! or ¡Vive la vida! )
'vive' is informal (implicit pronoun 'Tú') and 'viva' is formal (implicit pronoun 'Usted')
Live life to the fullest!
¡Vive la vida al máximo!
'Vivir la vida' is probably as close as you can get.
