The French comparative of adjectives has the same structure as the English compound comparative (This chair is more comfortable than the yellow one.)
Comparative of French adjectives
plus + adjective + que (= superiority)
Il est plus beau que lui.*
He is more beautiful than he.
aussi + adjective + que (equality)
Il est aussi beau que lui.*
He is as beautiful as he.
moins + adjective + que (subordination)
Il est moins beau que lui.*
He is less beautiful than he.
* There is a little specialty with the structure: after the comparing que is the unconnected personal pronoun. In common language in English this is also used quite often (She is more beautiful than him.). Therefore, this should not be much of a problem, right?
