Connecting your ideas makes your spoken Thai sound much more natural.

You can stop relying on short, robotic sentences by learning a few basic conjunctions.

Thai conjunctions are vocabulary words that link two thoughts together.

They’re extremely easy to use because Thai grammar doesn’t require verb conjugation.

You simply place the conjunction between two clauses and keep talking.

Here’s a breakdown of the most common Thai conjunctions you need to know.

And (และ / กับ)

The word for “and” in Thai depends on what exactly you’re connecting.

We use กับ (gàp) to connect nouns or people.

We use และ (láe) to connect full sentences, ideas, or verbs.

But (แต่)

Expressing contrast in Thai is very straightforward.

The standard word for “but” is แต่ (dtàe).

You can also use แต่ว่า (dtàe wâa), which translates closer to “but that” or “however”.

Both are used exactly like the word “but” in English.

Because (เพราะ / เพราะว่า)

Giving reasons is essential for building complex sentences.

The Thai word for “because” is เพราะ (prɔ́).

Native speakers frequently add ว่า (wâa) to make it เพราะว่า (prɔ́ wâa).

There’s absolutely no difference in meaning between the two.

Or (หรือ)

Offering choices requires the conjunction หรือ (rǔu).

It sits right between the two options you’re presenting.

In casual spoken Thai, you’ll often hear people pronounce this as หรอ (rɔ̌ɔ) when it lands at the end of a sentence.

If (ถ้า)

Creating conditional sentences is done using ถ้า (tâa).

You place it at the very beginning of the condition clause.

Thai doesn’t require a specific “then” word in the second clause to complete the thought.

However, you’ll often hear the linking word ก็ (gɔ̂ɔ) used right before the verb in the result clause.

Therefore / so (ดังนั้น / ก็เลย)

Connecting a cause to an effect helps your speech flow beautifully.

The formal word for “therefore” is ดังนั้น (dang-nán).

In everyday casual conversation, Thai people almost always use ก็เลย (gɔ̂ɔ ləəi) instead.

ก็เลย (gɔ̂ɔ ləəi) functions exactly like “so” in English.
