upend

Synonym discussion
Sense: verb/1
All four words describe moving an object from an upright to a non-upright position, but they differ in scope and register. 'Upend' specifically means lifting one end so the object stands on its top or falls onto its side; it is often deliberate and controlled. 'Overturn' is more formal and usually implies a complete turn that leaves the object upside down — commonly used for vehicles (the car overturned) or legal decisions (the ruling was overturned). 'Tip over' is the most conversational option and suggests an accidental or easy motion (a glass tipped over). 'Flip' describes a fast, light rotation, often in the air (flipping a pancake). 'Capsize' is restricted to boats and ships in water. For everyday cleaning or rearranging, you might say 'upend the bucket to drain it'; for an accident at the dinner table, 'tip over the glass' sounds more natural; for a courtroom context, only 'overturn' will fit.

Etymology
Formed by combining the prefix 'up-' (meaning to a higher position) with the noun 'end' (the tip or extremity of something). The word literally means 'to set on end' and was first recorded in English in the early 1800s. It originally described lifting the end of an object to stand it upright; over time it also came to mean tipping something over completely.
