Tính từ trong tiếng Anh

Đứng trước danh từ

Ví dụ: Many countries in the world have focused on sustainable development.

– Đứng sau các động từ như: be, appear, get, become, seem, look, smell, taste, feel

Ví dụ: Action movies with violent scene seem unsuitable for children.

– Find/ make/ keep + Object + Adj

Ví dụ: I find cooking very relaxing and rewarding.

2. So sánh hơn, so sánh nhất

2.1. Tính từ ngắn (đơn âm)

Đối với tính từ ngắn (đơn âm), ta thêm đuôi –er đối với so sánh hơn và đuôi –est đối với so sánh nhất. Nếu tính từ được hình thành từ phụ âm + nguyên âm đơn + phụ âm (không phải âm câm), phụ âm cuối cùng phải được nhân đôi trước khi thêm đuôi –er hoặc –est.

Tính từ So sánh hơn So sánh nhất
short shorter the shortest
long longer the longest
thick thicker the thickest
thin thinner the thinnest

2.2. Tính từ dài (có 2 âm tiết trở lên)

Đối với tính từ có 2 âm tiết, chúng ta chia thành 2 trường hợp:

  • So sánh hơn thì thêm đuôi -er, so sánh nhất thì thêm đuôi –est với những từ có tận cùng là –y, -le, -ow. Những từ có đuôi tận cùng bằng –y thì phải đổi “y” thành “i” rồi sau đó mới thêm đuôi.
  • So sánh hơn kém thì thêm more/ less trước tính từ, so sánh nhất thì thêm the most/ the least trước tính từ.
Tính từ So sánh hơn So sánh hơn nhất
busy busier the busiest
gentle gentler the gentlest
narrow narrower the narrowest
serious more serious the most serious

2.3. Tính từ có từ 3 âm tiết trở lên

Tính từ với ba hoặc nhiều âm tiết tạo thành sự so sánh bằng cách thêm more phía trước tính từ, và đặt most trước tính từ so sánh hơn nhất.

Tính từ So sánh hơn So sánh nhất
beautiful more beautiful the most beautiful
disappointing more disappointing the most disappointing

2.4. Trường hợp ngoại lệ

Tính từ So sánh hơn So sánh nhất
good better the best
bad worse the worst
far further / farther the furthest/ the farthest
little less the least
