Synonym discussion

Sense: verb/1

All four verbs describe moving quietly, but each has a different emphasis. Sneak focuses on avoiding notice — you sneak when you do not want anyone to see you go somewhere or do something. Creep emphasises slow, cautious movement, often to avoid making noise: you might creep up the stairs at night, but not necessarily in secret. Slink suggests moving in a way that shows guilt, shame, or fear — someone who slinks away after losing an argument looks defeated. Tiptoe describes the physical action of walking on the balls of your feet to stay quiet, without any implication of secrecy or guilt. For example: 'Henrik sneaked into the kitchen to grab some cake' (secretly, avoiding detection), but 'the nurse tiptoed past the sleeping patient' (carefully, only to avoid noise).

Etymology

Old EnglishOld NorseEnglish

The verb sneak first appeared in English in the late 1500s, possibly from an Old English word snīcan meaning 'to creep, crawl'. Related forms include the Old Norse snīkja ('to sneak, snatch') and the dialectal English snike ('to creep about'). The noun form meaning 'informer' emerged in the 1800s, and the use for shoes (sneakers) arose in the late 1800s because the rubber soles allowed silent, sneaky movement. The adjective use in compounds like sneak preview dates from the early 1900s.
