愾 (kǎi, kai4) is a literary character for a deep, audible sigh; it also means anger or resentment in established compounds. You meet it in the Shijing's lament for Zhou's capital. Sent alone, it signals deliberate classical diction, not an everyday reaction.

Text symbol

What 愾 means

It means a long sigh, or literary anger and resentment.

You meet it in the Shijing's Xia Quan: 愾我寤歎,念彼周京 — waking with a sigh, longing for Zhou's capital. That is political grief, not a texted sigh. Built around 氣 for sound, it later leans toward anger and shared hostility in fixed compounds, close to 慨 and 喟.

Literary and rare alone; clearest for anger inside fixed compounds.

Is 愾 safe to send alone? Usually no: add surrounding words if you mean anger.

Why does 愾 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.
