Frequently Asked Questions
What's the difference between 'juro' and 'prometo'?
'Juro' (I swear) is generally stronger and more emotional than 'prometo' (I promise). You use 'juro' to insist that something is true or to make a very solemn vow, almost like taking an oath. 'Prometo' is also for making a promise, but it can feel a bit more formal or neutral.
