The adjectives describe a noun or a pronoun .

Comparison of adjectives (as….as ).

not as + adjective +as

when we compare people , things , or events which are different .

Examples : The boys are not as tall as their father 

               Ahmad is not as strong as his old brother 

The +  adjective + est

when we compare three or more people , objects , or events .

Example : Giraffes are the tallest of all the animals . 

spelling rules

when an adjective ends in e , we add only r or st

example : white , whiter, whitest

when an adjective ends in y , we usually change the y to i , and dd er or est 

example :happy , happier, happiest

when an adjective ends in consonant – vowel – consonant , we double the last letter and add er or est

example : big , bigger , biggest

( we never double the letters w, x, y )

we use :

more + adjective (than ) or less + adjective (than )

when we compare two people, objectives or events.

examples: your car is more expensive than mine

              This lesson is less boring than yesterday’s  lesson

we  put the words more, less, the most , the least  in front of adjective which have three or more syllables .
