Usage Note

The word 'thong' for this type of shoe is common in British English, Australian English, and New Zealand English. In American English, this shoe is more commonly called a 'flip-flop'. In Australian English, 'thongs' is the default term — do not confuse with the underwear sense, which is clear from context. The singular form ('a thong') exists but is less common than the plural ('thongs').

Common Mistakes

I packed my thong for the gym.
I packed my thongs for the beach.
'thongs' (sandals) are for casual warm-weather wear, not for the gym. 'thong' (singular) more often refers to underwear.
He walked through the office wearing thongs.
He walked through the office wearing flip-flops.
In American English, 'thongs' refers to underwear; use 'flip-flops' or 'sandals' for the shoe sense in the US.

Synonym discussion

Sense: noun/3

All four words describe open footwear, but they differ in style and regional usage. 'Flip-flop' is the standard American English term for a flat rubber or plastic shoe held on by a V-shaped strap between the toes — Americans rarely use 'thong' for shoes. 'Sandal' is the broadest category and can include flip-flops, slides, and strappy dress sandals; it does not specifically require the toe-strap design. 'Slide' is a backless shoe with a wide strap across the top of the foot but no toe piece — it is easier to slip on and off than a flip-flop. 'Slipper' is typically worn indoors and may be made of soft fabric or fleece, whereas flip-flops and thongs are outdoor footwear. Example: 'Benjamin wore rubber flip-flops to the pool in California, but his Australian friend called the same shoes thongs.'

Etymology

Proto-GermanicOld EnglishMiddle EnglishEnglish

From Old English 'þwang' (a narrow strip of leather), tracing back to Proto-Germanic '*thwangaz'. The word has been used for leather fastenings since before written English. The sandal sense (a shoe with a thong between the toes) emerged in the mid-20th century, and the underwear sense rose to popularity in the 1980s and 1990s as fashion trends shifted toward minimal-coverage garments.
