spiral
spiral: [16] Spiral comes via French spiral from medieval Latin spīrālis ‘coiled’, a derivative of Latin spīra. This in turn went back to Greek speira ‘coil’. English also acquired the noun, as spire [16], which is used for the ‘tip of a spiral shell’. It is not the same word as the spire of a church [OE], which originally meant ‘stalk, stem’, and may go back ultimately to the base *spī- (source of English spike ‘pointed flower head’ and spine). The spiraea [17] is etymologically the ‘coiled’ plant; and spiraea in turn was used to form the term aspirin.
=> aspirin, spiraea
