Thong/Flip-flop人字拖的英文及法文

Thong [countable]
1 a long thin piece of leather used to fasten something or as part of a whip
2 [usually plural] American English a type of shoe that covers the bottom of your foot, with a strap that goes between your toes to hold it on your foot as you walk [= flip-flops]
3 a piece of underwear or the bottom half of a bikini that has a single string instead of the back part

"Thong" est en effet (normalement) "string"...

thong also used to mean flip-flop, until the "other" thong became popular about 20 years ago... Now you will always assume un string if you hear thong in AE. Except for your grandmother, who still walks on the beach with her thongs on her feet!
