What does foundered mean?
'Foundered' is the past form of the verb 'founder', meaning to fail utterly or collapse — most literally when a ship takes on water and sinks, and by extension when a company, negotiation, marriage, or plan breaks down completely. The word carries a tone of finality: something that founders does not merely stumble but goes under, often despite earlier promise. Journalists reach for it when reporting corporate collapses and failed ventures, while sailors use it in its original maritime sense. A distinct veterinary sense applies to horses suffering laminitis, commonly called founder. The term derives ultimately from the Latin 'fundus', meaning bottom, via Old French — fittingly, the fate of a foundered vessel. Because it resembles both 'founded', its near-opposite, and 'floundered', which describes struggling rather than sinking, careful writers distinguish it deliberately. It remains a precise, evocative choice wherever total failure is the story.
verb (past tense and past participle)To have sunk, collapsed, or failed utterly — literally of a ship filling with water, or figuratively of an enterprise, plan, or animal breaking down.
- (of a ship or vessel) To become filled with water and sink.
- (of a plan, enterprise, or undertaking) To fail completely or collapse.
- (of livestock, especially horses) To suffer laminitis — inflammation of the laminar tissue of the hoof, also called 'founder'.
"The startup foundered within a year, unable to secure a second round of funding."
"The ferry foundered in heavy seas off the northern coast, forcing all hands to abandon ship."
"Without fresh capital, the once-promising company simply foundered."
The word for sinking ships comes from the Latin word for 'bottom' — so when a plan founders, it has literally met its fundus.

Etymology of foundered
'Founder' entered English in the Middle Ages from Old French 'fondrer', meaning to sink or fall to the bottom, which itself descends from the Latin 'fundus', meaning bottom or base. The same Latin root gave English words such as 'foundation', 'fund', and 'profound', making 'founder' etymologically a word about reaching the bottom. A separate verb 'founder', used of casting metal, comes instead from the Latin 'fundere', to pour or melt, though in modern usage the failure sense dominates entirely.

How foundered is actually used
Formal to neutral register; common in journalism, business writing, and maritime accounts. In equine contexts, 'founder' names a specific hoof disease (laminitis), a wholly separate veterinary sense. The spelling-similar 'flounder' is frequently substituted in error.
Easily confused with foundered
To flounder is to struggle clumsily or thrash about without progress, whereas to founder is to sink or fail outright; floundering is struggling, foundering is going down.
'Founded' means established or brought into being, nearly the opposite outcome of 'foundered', which denotes collapse or failure.
