What 청 means
By itself, it has a sound, not a fixed meaning. Read it inside its full Korean word to see which meaning fits.
Some Korean vocabulary uses Hanja (Chinese characters used in Korean writing) for roots whose Korean sounds are written in Hangul. The Korean word 청년 (“young person”) uses 靑 for 청; 청을 들어주다 (“grant a request”) uses 請.
청 is one Hangul syllable block.
청 brings together the Hangul letters ㅊ, ㅓ and ㅇ in a single syllable block.
Hangul was devised in 1443 to make Korean easier to write. Hunminjeongeum, a book explaining the writing system, was published in 1446. Those dates belong to Hangul, not to the first appearance of this particular syllable.

1Why does 청 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
