second-wave

The term "second-wave" is a modern compound noun, later used adjectivally, built from two deeply rooted English words. "Second" originates from the Latin secundus, meaning "following" or "next," derived from the verb sequi (to follow), which establishes its core meaning of sequential order. "Wave" stems from the Old English wafian, describing a back-and-forth motion, later expanding metaphorically to describe any patterned surge or trend, like a wave of water. Combined in the mid-20th century, the term logically constructs the meaning of a subsequent, distinct phase of a movement, most famously applied to "second-wave feminism" of the 1960s-80s, which followed the first-wave fight for suffrage. The compound elegantly uses the imagery of sequential oceanic waves to conceptualize historical and social developments occurring in distinct, impactful stages.

Structure: second (numerical order) + wave (movement/pattern) - second: From Latin secundus (following, next), from sequi (to follow). In this compound, it functions as a numerical adjective indicating sequence. - wave: From Old English wafian (to wave with the hands). In this compound, it functions as a noun metaphorically denoting a rising trend, pattern, or surge of activity.
