Flip-flop is a word that suggests an action, a reduplicative word from early modern English.
· 16th century (1520s): Related echoic forms like flip-flap described loose, flapping movements or sounds.
· 17th century: The term “flip-flop” referred to anything that flaps, reverses, or moves back and forth, such as a flapping sound, a somersault, or something physically turning over.
Footwear Meaning (Modern Common Usage)
By the late 1950s and into the 1960s, “flip-flop” had become the prevailing term in both American and British English for rubber or plastic thong sandals, a name derived from the characteristic sound they made when walking. [etymonline.com]
Although similar sandal designs have been utilized for millennia across regions such as Egypt, India, and Japan, the term itself is of contemporary origin rather than ancient. The style that achieved widespread popularity in the United States was significantly influenced by the Japanese zōri, introduced domestically by U.S. soldiers returning after World War II.
Figurative Meaning (Politics, Policy, Opinion)
- Late 19th to early 20th century:
Flip-flops acquire a figurative sense, meaning:
A complete or abrupt reversal of position or direction
- This sense grew naturally from the physical idea of turning over or alternating states. By around 1900, it was used metaphorically and later became especially common in political language to criticize inconsistency.
Example:
“The candidate flip-flopped on taxes.”
“When I asked her to marry me, she flip-flopped with her answer."
Technical Meaning (Electronics)
- 1930s onward:
In electronics, a flip-flop is a binary switching circuit that alternates between two stable states (on/off, 0/1).
This use again reflects the core idea of alternation and reversal.

Bottom Line
All definitions of flip-flop derive from a core concept:
alternation—movement, sound, or position shifting back and forth
Whether referring to footwear, politics, or electronics, the term consistently denotes notions of instability, reversal, or rhythmic switching, originating from sound imitation rather than abstract theorization.
