Hangul syllable 뛸

It means “that will run or jump.” 뛸 is the form of 뛰다 placed before a noun to describe an action that has not happened yet. In 뛸 사람, it means “a person who will run or jump.” The same verb can describe a heartbeat or a price going up; the surrounding phrase sets the reading.

Hangul was created in 1443 and explained in Hunminjeongeum, a book published in 1446, as a way to make Korean easier to read and write than through Chinese-character-based writing. It later appeared in Buddhist and Confucian translations, practical books, and everyday labels.

A Hangul syllable arranges its starting consonant, vowel, and ending consonant in one square block. Fonts can change the proportions without changing 뛸. Text normalization can also represent it as separate Hangul letters, called jamo, instead of one precomposed syllable.

What if someone sent only 뛸?

It is a phrase fragment, not a fixed reaction. This form normally modifies a noun that follows, so by itself it leaves the described person or thing unstated. Read it with the surrounding Korean words to tell whether the action is running, jumping, a heartbeat, or rising prices.
