粉可以落在兩個地方
兩個意思共用同一份材料，只是粉的位置不同：一個在裡面，一個在表面。
adjective · B2
Looking or feeling like powder — made of very small, dry, loose bits — or breaking into such bits very easily when you touch it.
粉狀的、一碰就散的
核心畫面
Everything here comes out of the ending. Add -y to a noun and English gives you a word that means 'having something to do with that thing' — but it leaves it open whether the thing IS that, or merely HAS it on it. Dusty works the same way. So powdery puts fine dry powder somewhere in the picture and lets the sentence say where: inside the thing, so that it and runs through your fingers, or lying on top of it, like flour on a baker's hands.

這個字的一切都從字尾長出來。名詞加上 -y，英文就給你一個「跟那樣東西有關」的形容詞——但它刻意不說清楚：是本身就是那樣，還是上面沾了那樣。dusty 也是同一個做法。所以 powdery 只負責把「細細的乾粉」放進畫面裡，至於粉在哪裡，由句子決定：在裡面，所以一碰就從指縫流掉；或在表面，像麵包師傅手上的麵粉。同一個字，同一種東西，兩個位置。From the word’s history
Recorded simply as powder plus -y, the ordinary English ending that turns a noun into an adjective.
依據來源，這個字就是 powder 加上 -y——英文最常見的那個「名詞變形容詞」字尾。也因為 -y 本身不指定「是」還是「沾了」，這個字才會同時有兩個落點。
