串 chuàn
Definition: Measure word for things strung together or in a row/a skewer (of food)
串 is a character that looks like its definition: two square items on a stick! This can help you remember that its definition refers to things strung together on a line, or stuck on a skewer.
If you are in China, you will encounter this character a lot when you go for a snack. 串 is the word for grilled food on a skewer or kebab, such as 羊肉串 (yángròuchuàn, lamb skewers), 鸡肉串 (jīròuchuàn chicken skewers), or 蔬菜串 (shūcàichuàn vegetable skewers)
