Chú ý:
- 1.Những tính từ ngắn kết thúc bằng một phụ âm mà ngay trước nó là nguyên âm duy nhất thì chúng ta
nhân đôi phụ âm lên rồi thêm "er" trong so sánh hơn và "est" trong so sánh nhất.(ex:hot-->hotter/hottest)
-2.Những tính từ có hai vần,kết thúc bằng chữ "y" thì đổi "y" thành "i" rồi thêm "er" trong so sánh hơn và "e
st" trong so sánh nhất
+ happy ==> happier/happiest
+ easy ==> easier/easiest
+ heavy ==> heavier/heaviest
- 3.Những tính từ/trạng từ đọc từ hai âm trở lên gọi là tính từ dài,một âm gọi là tính từ ngắn.Tuy nhiên,một
số tính từ có hai vần nhưng kết thúc bằng "le","et","ow","er"vẫn xem là tính từ ngắn
