/kənˈsjuːm/
[verb] To use something completely, eat or drink something, or to destroy something entirely. It can also describe a strong feeling or desire that takes over a person's thoughts completely.
The Latin root means 'to take everything together' — consume was originally about total destruction, not shopping.
The word 'consume' travels back to the Latin verb 'consumere', which was built from two parts: the prefix 'con-', meaning 'together' or 'completely', and 'sumere', meaning 'to take' or 'to pick up'. So at its most literal, 'consumere' meant 'to take up completely' — to seize something so thoroughly that nothing was left behind. This was language built around the idea of total absorption, of something being swallowed whole by a greater force.
In classical Latin, 'consumere' carried a distinctly dramatic weight. Roman writers used it to describe fire devouring a building, time eating away at a person's life, or disease hollowing out a body. There was nothing gentle about the word. When Virgil or Cicero reached for 'consumere', they were reaching for a word that meant complete and irreversible loss. The object of the verb never survived the encounter intact.
The word moved through Old French as 'consumer', keeping much of its destructive energy, before arriving in English in the late 14th century. Early English uses closely followed the Latin sense — to consume was to destroy, to waste, to bring to nothing. Fire consumed forests; wars consumed armies; grief consumed the heart. The word appeared naturally in religious and poetic writing, where ideas of burning, sacrifice, and ruin were central themes.
Over the following centuries, English gradually softened and widened the word's meaning. By the 16th and 17th centuries, 'consume' had stretched to include eating, drinking, and the using up of resources — still the idea of something being entirely used, but without the catastrophic violence of the original. A candle consumed its wax; a traveller consumed food and drink. The destruction was quieter, more domestic, but the core idea of total use — of leaving nothing behind — remained.
The word's most modern sense, connected to buying goods and economic activity, developed strongly in the 18th and 19th centuries alongside the rise of trade and industry. A 'consumer' in this sense is someone who uses goods rather than produces them. It is striking that a word once reserved for fire and plague and ruin has become the central term of modern economic life. 'Consumere' — to take everything — now describes the ordinary act of purchasing a cup of coffee or scrolling through an online shop.
The same Latin root 'sumere' flows through several other familiar English words. Latin 'sumere' became the basis for 'assumere' (to take to oneself), which gave English 'assume' via Old French 'assumer'; for 'resumere' (to take again), which became 'resume' through Old French 'resumer'; and for 'praesumere' (to take beforehand), which passed through Old French 'presumer' to give us 'presume'. Each word carries that same fundamental idea of taking or grasping — 'consume' simply takes the most completely of all.
