Detailed Explanation
When to use chẳng những
Chẳng những implies a higher degree of something or an additional point that is especially significant, surprising, or perhaps even unexpected. It adds more emphasis to the second clause. Think of it as "not only X, but even Y" or "not only X, but Y (which is more remarkable)". It often carries a slightly stronger emotional weight, whether positive (admiration) or negative (disappointment/criticism).
For example, if you say someone is not only smart but also humble, using chẳng những would highlight that humility is an exceptional quality to find alongside intelligence, making the person even more admirable. In a negative context, it can express an escalation of problems, such as "not only is it broken, but it's completely beyond repair."
Historically, the chẳng component comes from a Hán-Việt root related to negation (不). The những acts as an intensifier or a pluralizer, so together it emphasizes "not just this, but all these or even more".
When to use không chỉ
Không chỉ is the more common and neutral way to say "not only". It simply connects two points where the second point is an addition to the first. It doesn't typically carry a strong emotional tone or imply surprise in the same way chẳng những does. It's versatile and can be used in almost any context where you want to list multiple attributes, actions, or conditions.
For instance, stating "the food is not only delicious but also healthy" with không chỉ is a straightforward declaration of two positive qualities. There's no particular emphasis on the "healthy" aspect being more remarkable than the "delicious" aspect; both are presented equally as additional information.
The Hán-Việt origins of không (空/無) meaning 'empty/not' and chỉ (止) meaning 'only' combine to form 'not only', making its meaning quite direct and unambiguous.

Common Patterns
Both chẳng những and không chỉ are most commonly followed by mà còn or mà thôi to introduce the second clause ("but also" or "but just"). While often interchangeable, the choice between them dictates the nuance.
Không chỉ A mà còn B: This is the most standard and neutral construction for "not only A but also B." It's versatile and widely used. Chẳng những A mà còn B: This pattern adds a layer of emphasis to B, making it seem more significant, surprising, or an escalation of A. It often implies that B is even more remarkable or unexpected than A. Không chỉ A mà thôi: Used to express "not just A, but that's all" or "not just A, but nothing more." It can also introduce a contrast. Chẳng những không... mà còn...: This strong negative pattern emphasizes a failure to do something and then an even worse action. For instance, "chẳng những không giúp đỡ mà còn gây thêm rắc rối" (not only didn't help but even caused more trouble). This construction feels much stronger with chẳng những.
Common Mistakes
Mistake 1 — Using chẳng những in overly neutral contexts without needing emphasis
While often interchangeable, using chẳng những in very plain, factual statements can sound a bit overly dramatic or formal when không chỉ would be more natural.
❌ Tôi chẳng những thích cà phê mà còn thích trà.
✅ Tôi không chỉ thích cà phê mà còn thích trà.
Why it's wrong and how to fix it: Liking coffee and tea is a very common and neutral preference. Using chẳng những here makes it sound like liking tea is an extraordinarily surprising or remarkable addition to liking coffee. Không chỉ is much more appropriate for such simple, everyday statements.
Mistake 2 — Incorrectly pairing with mà thôi
While both can pair with mà thôi, the nuance changes significantly. Chẳng những... mà thôi is less common and often sounds awkward or overly emphatic if the context isn't right.
❌ Học tiếng Việt chẳng những cần từ vựng mà thôi.
✅ Học tiếng Việt không chỉ cần từ vựng mà thôi.
Why it's wrong and how to fix it: The phrase "không chỉ... mà thôi" means "not only... but that's it" or "not just..." This is a very natural way to introduce a more comprehensive idea. Using chẳng những here forces a strong emphasis that isn't typically aligned with the "mà thôi" structure, which tends to limit or qualify. The common pattern is không chỉ A mà còn B OR không chỉ A mà thôi (meaning "not just A").
Mistake 3 — Misinterpreting the emphasis
Sometimes learners use chẳng những intending to simply add information, but inadvertently inject an unintended emphasis or slight judgment.
❌ Cô ấy chẳng những là giáo viên mà còn là mẹ của hai đứa trẻ.
✅ Cô ấy không chỉ là giáo viên mà còn là mẹ của hai đứa trẻ.
Why it's wrong and how to fix it: Being a teacher and a mother of two is a common combination of roles, not inherently surprising or remarkably challenging to an extent that demands chẳng những. Using chẳng những here might suggest that being a mother of two is an extraordinary feat in addition to being a teacher, which might not be the intended nuance. Không chỉ offers a neutral way to present these two facts.

Answer
Correct answer: chẳng những (or không chỉ, depending on nuance)
Cuốn sách này chẳng những dạy tiếng Việt mà còn giới thiệu về văn hóa Việt Nam.
Explanation: While không chỉ would also be acceptable here for a neutral statement, chẳng những is a great choice if you want to emphasize that learning about Vietnamese culture is a particularly valuable or enriching bonus beyond just language learning, making the book even more comprehensive. It highlights the "even more" aspect. If it were a simple factual statement, không chỉ would be fine, but the option with more emphasis is chẳng những.
