Sentence Connectors (연결어미)¶

Sentence connectors are grammatical endings that link clauses together, allowing you to express complex ideas in a single flowing sentence. They are essential for natural Korean speech and writing.

Why Connectors Matter¶

In Korean, stringing together multiple simple sentences sounds choppy and unnatural:

Choppy: 저는 집에 갔어요. 저는 밥을 먹었어요. Natural: 저는 집에 가서 밥을 먹었어요.

Connectors create the flow that native speakers use constantly in everyday conversation.

Types of Connectors¶

Sequential and Simultaneous Actions¶

-고: Links actions in sequence or happening at the same time

-서: Natural consequence, objective reason
-니까: Subjective reason, stronger connection to the result

Contrast and Background¶

-지만: Direct contrast, "but/however"
-는데: Sets context, softer contrast, introduces background information

Common Patterns¶

Most connectors attach to verb stems and follow predictable patterns:

Verb stem + connector ending
Some require different forms based on tense
Consonant vs vowel endings may differ

Learning Strategy¶

Start with -고 and -서 as they're the most frequently used
Master the nuanced differences between similar connectors (-서 vs -니까, -지만 vs -는데)
Practice each connector in multiple contexts
Listen for these patterns in Korean media to understand natural usage

Important Notes¶

The first clause with a connector typically does NOT take tense markers (past/future)
The tense is usually shown only in the final verb of the sentence
Some connectors can be used in both formal and informal situations, while others are more restricted
