喜樂美語
  1. 1（名詞）螺旋（形）；（動詞，常用於負面）急遽惡化

    A shape that curves around and around, getting bigger or smaller as it goes - like a spring, a spiral staircase, or a snail's shell. As a verb, 'to spiral' means to move in that curving pattern, and it is often used for something getting worse and worse very quickly and out of control - 'prices spiraled out of control.'

From the word’s history

From Middle French spirale, from Medieval Latin spiralis, from Ancient Greek σπεῖρα 'coil'.

源自拉丁文 spiralis，來自古希臘文 σπεῖρα「線圈、盤繞」。

Wiktionary

組成Comes from an old Latin word for 'a coil,' which itself came from an older Greek word with the same meaning.
