Explications :

* On utilise les adjectifs pour faire la comparaison :

- We add er to short adjectives which contain one syllable:

      EX :  adj + er + than

       fast --> faster

- We add r to short adjectives ending in e :

          EX :   adj + r + than

         safe --> safer

- We must double the consonant when short adjectives end with one vowel and one consonant :

EX : big -->bigger + than

- We must change  y to i  and add  er to adjectives with two syllables ending in y :

EX : busy --> busyier  --> busier + than

_ We usually add more or less to other adjectives with two or more syllables :

EX : more + adj + than

        more beautiful

        less + adj + than

- less expensive

EXCEPTIONS :

   bad --> worse

   good --> better

   far --> farther/further
