Synonym discussion

Sense: verb/1

All four words describe moving something from one position to another, but they differ in formality and specificity. 'Invert' is the most precise and formal term — it specifically means turning the top to the bottom or the inside out, and it is common in technical, scientific, and written English. 'Turn over' is the everyday, neutral phrasal verb that native speakers use in most situations; you turn over a pancake, a page, or a card. 'Flip' suggests a quick, casual, or even careless motion (flip a switch, flip a coin). 'Upset' is a formal or literary word meaning to tip something over, often accidentally, and is far less common today. Example: 'She inverted the cake pan onto a plate' sounds like a written recipe; 'She turned the cake pan over' is what you would say in the kitchen; 'She flipped the pancake' describes a quick wrist motion.

Etymology

LatinFrenchEnglish

The word 'invert' comes from Latin 'invertere', meaning 'to turn in, to turn about, to change'. This was formed from 'in-' (meaning 'in, into') and 'vertere' (meaning 'to turn'). It entered English through French in the 1500s, first used in the literal physical sense of turning something upside down, and later extended to the abstract sense of reversing order or relationship.
