Liên từ trong tiếng anh: Cấu tạo, cách dùng & bài tập áp dụng
Liên từ là từ dùng để nối hai phần, hai mệnh đề trong một câu. Sau đây là một vài ví dụ về liên từ:
Liên từ đẳng lập: and, but, or, nor, for, yet, soLiên từ phụ thuộc: although, because, since, unless. Ta
có thể xem xét liên từ từ 3 khía cạnh
1. Cấu tạo của Liên từ gồm 3 dạng chính:




Từ đơn ví dụ: and, but, because, although
Từ ghép (thường kết thúc bằng as hoặc that)ví dụ: provided that, as long as, in order that
Tương liên (đi cùng với trạng từ hoặc tính từ)ví dụ: so...that
2. Hai chức năng cơ bản của Liên từ:



Liên từ đẳng lập: được dùng để nối 2 phần trong một câu có vai trò ngữ pháp độc lập với
nhau. Đó có thể là các từ đơn hoặc các mệnh đề. Ví dụ:
- Jack and Jill went up the hill.- The water was warm, but I didn't go swimming.



Liên từ phụ thuộc: được dùng để nối mệnh đề phụ thuộc với mệnh đề chính của câu. Ví dụ: - I
went swimming although it was cold.
3. Vị trí của liên từ trong tiếng anh




Liên từ đẳng lập: luôn luôn đứng giữa 2 từ hoặc 2 mệnh đề mà nó liên kết
Liên từ phụ thuộc: thường đứng đầu mệnh đề phụ thuộc.
* Các tình huống giao tiếp tiếng anh thông dụng

Một liên từ đẳng lập nối các phần có vai trò ngữ pháp tương đương hoặc ngang bằng nhau trong câu.
Một liên từ đẳng lập cho thấy các thành phần mà nó liên kết có cấu trúc và tầm quan trọng tương tự
nhauHãy xem những ví dụ sau – 2 thành tố trong ngoặc vuông được nối với nhau bởi một liên từ đẳng

lập



I like [tea] and [coffee].
[Ram likes tea], but [Anthony likes coffee].
Liên từ đẳng lập luôn đứng giữa các từ hoặc mệnh đề mà nó liên kết.Khi một liên từ đẳng lập nối các
mệnh đề độc lập thì luôn có dấu phẩy đứng trước liên từ



I want to work as an interpreter in the future, so I am studying Russian at university.
Tuy nhiên, nếu các mệnh đề độc lập ngắn và tương tự nhau thì dấu phẩy không thực sự cần thiết:



She is kind so she helps people.
Khi “and” đứng trước từ cuối cùng trong một dãy liệt kê, thì có thể có dấu phẩy hoặc không




He drinks beer, whisky, wine, and rum.
He drinks beer, whisky, wine and rum.
Có một mẹo nhỏ để nhớ 7 liên từ ngắn và đơn giản.F A N B O Y SFor And Nor But Or Yet So
 Liên từ phụ thuộc
Phần lớn số liên từ là liên từ phụ thuộc. Một số liên từ phổ biến như



after, although, as, because, before, how, if, once, since, than, that, though, till, until, when,
where, whether, while
Liên từ phụ thuộc nối mệnh đề phụ với mệnh đề chính Hãy xem ví dụ sau:
Mệnh đề chính liên từ phụ thuộc mệnh đề phụ Ram went swimming although it was raining
Một mệnh đề phụ thuộc “phụ thuộc” vào mệnh đề chính. Nó không thể đứng một mình như là câu độc
lập được. Hãy tưởng tượng xem nếu ai đó nói với bạn “ Hello! Although it was raining”, bạn sẽ hiểu
như thế nào? Vô nghĩa! Nhưng mệnh đề chính (hoặc mệnh đề độc lập) thì có thể đứng riêng một mình.
Bạn sẽ hiểu rõ ý nếu có người nói rằng: “Hello! Ram went swimming.”Liên từ phụ thuộc luôn luôn
đứng ở đầu mệnh đề phụ thuộc. Nó “giới thiệu” mệnh đề phụ thuộc. Tuy nhiên, mệnh đề phụ thuộc đôi
khi cũng có thể đứng sau hoặc trước mệnh đề chính. Do vậy trong tiếng Anh cũng có thể có hai cấu
trúc sau: Ram went swimming although it was raining.Although it was raining, Ram went swimming
Kiến thức nâng cao về Liên Từ trong tiếng anh:
Ngoài 2 loại liên từ (Liên từ phụ hợp-ordinating conjunction và Liên từ tương quan-correlative
conjunctions) chúng ta đã học ở Level 250-500, hôm nay tôi muốn cung cấp thêm một loại liên từ nữachủ điểm hay xuất hiện nhất trong luyện thi TOEIC. Liên từ này được gọi là Liên từ tương hợp
(Subordinating Conjunctions). Sau đây là một số loại liên từ tương hợp. Chú ý rằng, sau những liên từ
này là một mệnh đề. Đọc thêm về Câu điều kiện trong tiếng anh
