Read about how to make the comparative here.
Comparative structures: things or people that are the same
First, we can use 'as ... as' with a normal adjective (not a comparative) to say two things are the same:
- John is as tall as Luke (= they are the same height).
- The red shirt is as expensive as the blue shirt (= they are the same price).
- Lucy is not as tall as Helena (= Helena is taller than Lucy).
- Paris is not as big as London (= London is bigger than Paris).
We can say that something is more than another thing by using a comparative adjective with 'than'.
- France is bigger than Scotland.
- Luke is taller than Lucy.
- Your book is more interesting than my book.
- Canada is far bigger than Scotland.
- Your book is much more interesting than my book.
- Amanda is a lot younger than Julie.
- This exercise is a little more difficult than that exercise.
- Scotland is less big than France.
- Lucy is less tall than Luke.
- My book is less interesting than your book.
- That child is getting taller and taller.
- The climate is getting hotter and hotter.
- This city is becoming more and more crowded.
