gummy
adjective, nounOne picture covers this half of the word: gum, the thick sticky stuff that seeps out of a tree and to whatever it touches. Anything with that quality is gummy — sap on your hands, glue left behind by a sticker, rice that has at the bottom of the pot. And when someone makes a sweet with the same soft, springy, slightly feel, the sweet takes the name too.
From the word’s history
From gum (the substance) + -y; the noun's spelling was also pushed by German gummi.
來自 gum（那種黏稠的膠質）加上 -y。名詞的拼法還受到德文 gummi 的影響，所以 gummi 和 gummy 兩種寫法都看得到。

A second word, same spelling
gummy
adjectiveThis half of the word has nothing to do with stickiness. Here gum means the pink flesh that holds the teeth, and the picture is a mouth opening into a smile where the gums are what you see. A baby has no teeth yet; an older person may have lost theirs; some people simply show a lot of gum when they smile. The word points at what is showing, not at how anything feels.
From the word’s history
From gum (the flesh around the teeth) + -y. Wiktionary keeps this as a separate etymology from the sticky gum, so the two adjectives only look alike.
來自 gum（牙齦）加上 -y。來源辭典把它跟「黏膠」那個 gum 分成兩條不同的字源，所以這兩個 gummy 只是長得一樣、唸得一樣，意思上並不相通。
