Frequently Asked Questions
Why does the base verb 'garantizar' have a 'z' but sometimes changes to 'c'?
This is a spelling rule in Spanish! The letter 'z' always sounds like 's' (or 'th' in some regions) but it cannot be placed before the letters 'e' or 'i'. To keep the same sound when conjugating (like in 'garanticé' or 'garantice'), the 'z' must change to a 'c'.
Can I use 'garantizo' instead of 'prometo' (I promise)?
Yes, but 'garantizo' is generally stronger and more formal than 'prometo.' 'Prometo' is a simple promise, while 'garantizo' implies a certainty or backing (like a warranty).
