Yucky is the adjective that goes with yuck. It describes a thing that disgusts you: yucky food, a yucky smell, yucky green water in a vase of dead flowers.

Yucky這個字是yuck噁的形容詞，describes用來形容a thing that disgusts you讓你覺得噁心的東西：yucky food噁心的食物、a yucky smell噁心的味道，還有a vase of dead flowers插著枯花的花瓶裡那種yucky green water噁心的綠水。

The word sounds like a child, and that is its real character. Small children say it about vegetables. Adults use it playfully, or when talking to children, or lightly about something mildly unpleasant.

The word這個字sounds like聽起來像a child小孩子，that is its real character這才是它真正的味道。Small children小小孩about vegetables講到蔬菜的時候say it會這樣說。Adults大人use it playfully會好玩地這樣用，or when talking to children或是在跟小孩說話時，or lightly about something mildly unpleasant或是輕鬆地講某個有點不舒服的東西時。

Because of that, it is warmer and softer than the strong adult word disgusting — yucky almost sounds affectionate. "Take off those yucky socks" is not really an attack.

Because of that因為這樣，than the strong adult word disgusting比起大人常用的強烈字眼disgusting噁心，it is warmer and softer它更溫暖也更柔軟——yucky almost sounds affectionateyucky聽起來幾乎帶點疼愛的感覺。"Take off those yucky socks"把那雙髒兮兮的襪子脫掉is not really an attack其實不是真的在罵人。

It does stretch a little past the physical. People say a yucky day for grey, damp weather, or say they feel yucky when they are slightly ill — not properly sick, just off, heavy, not right. That is a common and useful use.

It does stretch a little past the physical它確實會稍微延伸到超出身體感覺的範圍。for grey, damp weather碰到陰濕的天氣，people say會說a yucky day，or說they feel yucky覺得yucky when they are slightly ill身體有點不舒服的時候——not properly sick不是真的生病，just off, heavy, not right只是怪怪的、悶悶的、不太對勁。That is a common and useful use這是很常見也很實用的用法。

Keep it out of formal writing. In a report or an essay, use unpleasant or unhygienic instead.

Keep it out of formal writing正式寫作裡不要用這個字。In a report or an essay在報告或論文裡，use改用unpleasant不舒服的or unhygienic instead或unhygienic不衛生的就好。
