founder

Pluralfounders

Formsfounders, foundering, foundered

1. 1
   nouncountable

   A person who establishes a company, project, organization, or state.

   The company's founder stepped down after twenty years at the helm.

   Each founder contributed their savings to launch the startup.

   Similarcreator, originator, architect, builder, initiator

   Note

   Three unrelated words share this spelling, and this is the only one built on the verb found plus -er, reaching English from Latin fundātor through Old French. The metal caster comes instead from Latin fundo, "pour, melt, cast," and the sinking verb comes from fundus, "bottom." Its natural opposite is ruiner, the one who brings down what a founder built.

2. 2
   verbintransitive

   Of a vessel, to fill with water and sink.

   The ferry foundered within minutes of striking the reef.

   Sailors scrambled to the lifeboats as their ship started to founder.

   Similarsink, submerge

   Oppositefloat

   Note

   Here the ship sinks without anyone sinking it, and the verb takes no object. Defoe's narrator in 1719 watches his ship go down and understands "for the first time what was meant by a ship foundering in the sea." Melville's Moby-Dick (1851) compares a preacher's voice to a bell tolling on a ship foundering in fog. The -ing form captures the slow, watched sinking well.

3. 3
   verbintransitive

   To fail or come to nothing; to break down.

   The merger foundered when the two boards could not agree.

   Without funding, even the best projects founder quickly.

   Similarfail, collapse, falter, fold, miscarry

   Oppositesucceed, thrive, prosper, flourish

   Note

   The sinking image carried over to plans and schemes long ago. Shakespeare and Fletcher wrote "All his tricks founder" in 1613. The subject is usually an undertaking, such as an ambition, a plan or a merger, and the verb takes no object. A 2024 article describes how much of Prescott's railway plan foundered after a derailment just south of Hatfield.

4. 4
   verbintransitive

   To stumble and fall, going lame in the process.

   The packhorse foundered under its heavy load.

   On icy ground, even sure-footed mules can founder.

   Similarstumble, collapse, stagger, fall

5. 5
   nouncountable

   A worker who casts metals into various forms by pouring molten metal into molds.

   The founder lifted the crucible and poured glowing metal into the sand mold.

   Each bell was cast by a founder who tuned it by shaving away thin layers of metal.

   Similarcaster, foundryman, molder

   Note

   Watch the construction: a founder of bells, cannon, hardware or printing types is someone who casts them, not someone who starts them up. The phrasing matches a founder of a company exactly, and only the object tells the two apart. Metal goods point here, while institutions point to the person who establishes something.

6. 6
   noununcountable

   A severe form of laminitis in horses, caused by untreated inflammation inside the hooves.

   The mare developed founder after weeks of standing on hard, dry ground.

   Chronic founder had already rotated the bone inside the horse's hoof.

   Similarlaminitis

   Note

   Horse owners and vets usually treat it as a condition rather than an event: a horse develops founder, or has chronic founder, with no article. It names the severe end of laminitis, when the inflammation in the hooves has gone untreated. It pairs with the verb for laming a horse, so a foundered horse is one suffering from founder.

7. 7
   verbtransitive

   To bring on inflammation and soreness inside a horse's feet or legs, leaving the animal lame or unfit for work.

   Overfeeding grain can founder a horse within days.

   He had foundered the mare by working her hard on frozen ground.

   Similarlame, cripple

8. 8
   nouncountable

   The chief furnace worker at an ironworks, responsible for running the furnace and the melt.

   The founder signaled the crew to open the furnace and tap the metal.

   Years at the furnace had made him the most trusted founder at the ironworks.

   Similarsmelter, furnaceman

   Note

   A job title from the British ironworks rather than a general word. H.R. Schubert's History of the British Iron and Steel Industry (1957) says the name was applied there "long afterwards" to the man in charge of the blast furnace and the smelting. The title came from the older word for a caster and passed to the worker who ran the furnace.

9. 9
   nouncountable

   A common ancestor of a population, especially one carrying a particular genetic mutation passed down through the group.

   Researchers identified the founder who introduced the mutation into the population.

   The rare disease was traced to a single founder several generations back.

   Similarancestor, progenitor, forebear

   Oppositedescendant

   Note

   Genetics often uses the word as a modifier, in phrases like a founder population, the founder effect and founder mutations. Counting founders can reveal history. Dennis Drayna, writing in Scientific American in 2006, explains that the sickle cell mutation's five haplotypes suggest it arose independently in five different founders, rather than spreading from a single ancestor.
