천둥

천둥 (cheon-dung) is the Korean word for thunder. It refers specifically to the loud, crashing, or rumbling sound that follows a flash of lightning.

Think of it as the 'voice' of the storm. When you are inside on a rainy day and hear a loud rumble, that is 천둥. It is a natural, powerful sound that often makes people feel small compared to the forces of nature.

In Korean culture, 천둥 is often paired with 번개 (lightning). While 번개 is the visual light, 천둥 is the auditory result. Understanding this distinction is key to describing weather accurately.

The word 천둥 has deep roots in the Korean language. Historically, it is derived from Sino-Korean roots, though it functions as a native-feeling noun in modern speech.

In ancient times, 천둥 was often associated with divine power or the anger of the heavens. Many cultures, including Korea, historically viewed thunder as a supernatural event, which is reflected in the gravity of the word itself.

Over centuries, the understanding of the term shifted from a mythological explanation to a scientific one. However, the emotional weight of the word remains, often used in literature to signify drama, sudden change, or impending conflict.

You use 천둥 primarily when discussing weather. It is a neutral, descriptive noun used in both casual conversation and formal weather reports.

Commonly, it is used with verbs like 치다 (to strike/happen). For example, 천둥이 치다 means 'thunder is striking/rumbling'.

In formal contexts, like news broadcasts, you might hear it as part of a weather forecast. In casual settings, it is just a simple way to describe why you might be scared of a storm or why your dog is hiding under the bed.

천둥 is a non-count noun in the sense that you don't usually pluralize it. You treat it as a singular phenomenon.

The pronunciation is straightforward: cheon-dung. The 'ch' is aspirated, and the 'dung' has a nasal ending. It rhymes with words like 중 (middle) in terms of the ending sound.

Grammatically, it is almost always the subject of the verb 치다 (to strike). You will rarely see it as an object of a verb other than in poetic or metaphorical contexts.
