In French we use the comparative “plus que” to express superiority between two people, two objects or two situations.
For example:
L’océan Pacifique est plus grand que l’océan Atlantique. The Pacific Ocean is bigger than the Atlantic Ocean.
Elle est plus intelligente que toi. She is smarter than you.
Remember:
When we compare the same possessions, it is better to use a possessive pronoun or in certain cases a demonstrative pronoun followed with the preposition “de” to avoid repetition.
