催し

🎉 催し = 催す (to hold, to host) + し: the thing that gets held, an event
催す means to hold or host. Its noun form 催し is whatever gets hosted, so any organized event or festival fits this word.
催 — person 亻 + 崔 (cuī, phonetic)
催 is a semantic-phonetic compound. The person radical 亻 gives the meaning, since urging or hurrying is something one person does to another, while 崔 supplies the sound 'cui'. The original sense was to press or push someone to act, which broadened to today's meaning of urging, hastening, or prompting.
