Meaning

快乐 means happiness or joy, describing a state of being happy and content. It combines 快 (fast, quick, pleased) and 乐 (happy, joy). This word emphasizes a more active, upbeat kind of happiness compared to other words like 幸福 (which suggests deeper contentment or well-being).

Usage

快乐 is commonly used in everyday conversation and especially in greetings and wishes, such as 生日快乐 (happy birthday) or 圣诞快乐 (merry Christmas). It tends to describe temporary states of happiness or moments of joy rather than long-term life satisfaction. Native speakers often use it to wish others well on special occasions.
