3. Meaning & Usage
The sentence endings –다, –ㄴ다, and –는다 are used in plain speech (also called declarative speech), and they are commonly used in writing and formal speech to express statements of fact or opinion. These endings are typically used in present tense for making simple statements or observations.
Here’s a breakdown of how each form is used:
