橙 – Cheng2 – Orange
Gotcha!, you’re thinking, I just KNOW he’s posted Orange before! Let me just pull up Google and…
Nice try, but you’re thinking of when I posted 橘, another word for Orange.
It looks like 橘子 refers to things in the Mandarin Orange family, and you use 柳橙 – Liu3 Cheng2 to mean “true” oranges. I didn’t even know there was a difference! You can read more on Oranges, and on Mandarin Oranges. In fact, if you have the time, you can read about all the Fruits of Warm Climates.
